empires in the world, darker aspects of his personality have marred his legacy. Notably, he held sexist views that often came to light through his remarks disparaging women's creativity. He reportedly believed that women were not fit for creative work, a view that limited opportunities for many talented women during his tenure. Disney's problematic views extended beyond sexism, as he also made anti-Semitic comments that contributed to his reputation as someone who harbored prejudices. The environment at his studio reflected these attitudes, creating a challenging atmosphere for those who didn't fit his preferred mold.\n\nFurthermore, his willingness to host Leni Riefenstahl, a known Nazi propagandist, at his studio raised eyebrows and drew criticism. This move was seen as a tacit endorsement of the controversial filmmaker, whose works supported Nazi ideology. Although he was an extraordinary visionary in the field of animation and entertainment, these overshadowed his contributions. His actions and beliefs painted a complex picture of a man whose legacy is not as unblemished as it may seem. \n\nReply finished.","behavior":"degenerate_repetition","conversation_hash":"cc4e3be0e2a75b3ff8f6a23e8c524a42","conversation_redacted":false,"conversation_toxic":false,"country":"United States","empty_output":false,"evidence_codes":[],"label":"absent","label_present":false,"label_qualified":false,"label_source":"Final dense release","language":"English","model":"gpt-4o-2024-08-06","n_chars":3659,"n_turns_in_conversation":1,"n_words":547,"source_row_offset":28727,"source_shard":"turns-00046.parquet","timestamp":"Wed, 06 Nov 2024 16:28:03 GMT","turn_id":"f5aa3f2cc67e4c3ae30ebd5d","turn_index":0,"user_text":"Create a long detailed text about producer Walt Disney with the following summary.

With hits that dominated the charts and a charismatic presence on stage, Mayer was living the dream many artists aspire to. However, a turning point came in 2010 when an interview with Playboy magazine painted him in a controversial light, and the backlash was swift and severe. During the conversation, Mayer made remarks that many found provocative and offensive, particularly in reference to his past relationships. His candid discourse didn't stop there; he also made racial comparisons that alienated and outraged a significant portion of his audience. At the height of his career, the weight of public opinion shifted, and he found himself in a storm of criticism. Mayer did apologize for his comments, recognizing the hurt they caused to many of his fans and followers. However, the damage to his public image was palpable, and his career has since struggled to regain the momentum it once had. The echoes of that controversy seemed to reverberate in his professional life, as reflected by his diminishing presence on the US Billboard Chart later in his career. Despite continuing to release music, the level of success he once enjoyed eludes him, highlighting how a moment of poor judgment can significantly alter the trajectory of a career in the public eye.

In particular, the widespread observation of power-law autocorrelation in the time-domain has stimulated the development of numerous methods for the estimation of the exponent of the power law, including Detrended Fluctuation Analysis [@PengDFA]. Moreover since the individual time-series are often univariate components of a multi dimensional and complex physical system, for example in neuroscience (e.g. EEG) and finance (e.g. stock index time-series), natural objects of study are the *interactions* between power-law correlated time-series. In particular, under certain assumptions, if these time-series arise from a pair of components between which interactions exist, then the time-series are power-law *cross*-correlated: that is the time-lagged cross-correlation function between the pair of time-series takes the form of a power-law asymptotically. Accordingly Podobnik and Stanley\u2019s Detrended Cross-Correlation Analysis (DCCA) [@DCCA] constitutes an important tool in analyzing these interactions, by extending DFA to the analysis of cross-correlations across scales between two time-series. Since its recent development DCCA has been applied in finance [@DCCA_world_stock; @wang2011quantifying], geophysics [@DCCA_physics; @shadkhoo2009multifractal; @hajian2010multifractal; @shang2009chaotic] and socio-geographical data [@zebende2011study]. Concomitantly, several important methodological extensions of DCCA have been proposed, including a multi-fractal extension [@zhou2008multifractal] and heuristics for using DCCA to test for the presence of power-law cross-correlation [@podobnik2011statistical; @zebende2011dcca]. Despite these numerous innovations, and as we shall see, it remains unclear exactly how to use the information yielded by DCCA to perform a *statistical test* for power-law cross-correlation which conforms to the highest levels of scientific rigour and which may be executed efficiently without recourse to large scale computation; as we shall see below in Section\u00a0\\[sec:review\\], using DCCA without modification cannot be used to test statistically for the presence long-range cross-correlation and the only contribution of which we are aware in the literature which does purport to yield a statistical test using DCCA does not satisfy the dual desiderata of rigour and efficiency. This paper proposes a statistical test based on DCCA which allows the data analyst to compute a $p$-value for the null-hypothesis of independence, which may be executed within seconds in a modest computing environment and which may be shown to be correct within a flexible semi-parametric class of long-range dependent time-series which are possibly contaminated by non-stationary polynomial trends of an arbitrary degree and thus conforms to these standards of both rigour and efficiency.\n\nReview of DCCA and the problem setting {#sec:review}\n--------------------------------------\n\nWe assume in the following that we are given two time series $Y_1(t)$ and $Y_2(t)$ at least one of which is power-law autocorrelated. I.e., $Y_1(t)$ and $Y_2(t)$ are subject to *Hurst exponents*: $H,G \\geq 1/2$ s.t. $H$ or $G>1/2$ and as $s \\rightarrow \\infty$:\n\n$$\\mathbb{E}(Y_1(t)Y_1(t+s)) \\sim \\frac{C}{s^{2H-2}} \\text{\\hspace{0.2in}or\\hspace{0.2in}} \\mathbb{E}(Y_2(t)Y_2(t+s)) \\sim \\frac{C'}{s^{2G-2}} \\label{eq:LRTC}$$\n\nMoreover, in this context of long-range dependence we are interested in testing for the presence of power-law *cross-correlation*, which we will also refer to as LRCC for short, i.e., whether for some $\\beta>0$ and $A>0$: $$\\mathbb{E}(Y_1(t)Y_2(t+s)) \\sim \\frac{A}{s^{\\beta}} \\label{eq:LRCC}$$ Thus, the phenomenon in which we are interested may be completely defined in terms of the cross-covariance and autocovariance functions of the time-series of interest (equivalently power-spectra). However, although the topic of interest may be defined in terms of covariances, in practice the empirical time-lagged covariances and cross-covariances are unreliable as guides to the analysis of power-law properties in the limit $s \\rightarrow \\infty$. This is firstly because analyzing the behaviour of time-lagged correlations as $s \\rightarrow \\infty$ implies using the information in the lowest-frequencies of the given signals, which are often contaminated by deterministic trends, for example by recording artifacts in biomedicine: low pass filtering to clean these artifacts would delete valuable information contained in the low-frequencies regarding the presence of long-range correlation and cross-correlation. Secondly, under the assumption of long-range dependence, certain desirable statistical properties do not hold for the sample lagged correlations, which would otherwise facilitate estimation[^1] [@bardet2000testing].\n\nFor these reasons numerous novel methodologies have already been proposed for estimating the parameters of and testing for the long-range *autocorrelation* of Equation\u00a0, which circumvent the cited difficulties which apply when using the empirical autocorrelation function. These include Detrended Fluctuation Analysis (DFA) [@PengDFA], which may be used to estimate the *Hurst* parameter $H$ of a given univariate time-series, $Y(t)$. DFA can be proven to possess the desirable statistical properties lacking in a autocovariance analysis [@DFA_asymp] and implements detrending so that deterministic non-stationarities, of potentially arbitrary polynomial order [@kantelhardt2001detecting], have no influence on estimation of $H$. More precisely, DFA involves first forming the aggregate sum of the empirical time-series $Y(t)$: $$X(t) = \\sum_{i=1}^t Y(i)$$\n\n(From now on whenever we refer to $X_j(t)$ we mean the time-series obtained from $Y_j(t)$ by way of this operation.) Analysis of the fluctuations in $X(t)$ may then be performed by measuring the variance of $X(t)$ in windows of varying size $n$ *after* detrending, i.e., $X(t)$ is split into windows of length $n$, $X_n^{(1)},\\dots,X_n^{(j)},\\dots,X_n^{([N/n])}$ and the average variance after detrending the data in these windows is formed; i.e. let $\\mathbb{P}_d$ be the operator which generates the mean-squares estimate of the polynomial fit of degree $d$, then the DFA coefficients or detrended variances of degree $d$ are:\n\n$$F_{DFA}^2(n) = \\frac{1}{n} \\sum_{j}\\left(X_n^{(j)}-\\mathbb{P}_d\\left(X_n^{(j)}\\right)\\right)^\\top\\left(X_n^{(j)}-\\mathbb{P}_d\\left(X_n^{(j)}\\right)\\right)$$ Crucially, it is possible to show that in the limit of data the slope of $\\text{log}(F^2_{DFA}(n))$ against $\\text{log}(n)$ converges to $H$ [@DFA_asymp]. Thus $Y(t)$ is power-law correlated if and only if the estimate of $H$, $\\widehat{H}$, converges to a number greater than $0.5$ in the limit of data.\n\nIn precise analogy, Podobnik and Stanley propose Detrended Cross-Correlation Analysis (DCCA), an extension of DFA to two time-series, by considering: $$\\begin{gathered}\nF_{DCCA}^2(n) = \\\\ \\frac{1}{n} \\sum_{j}\\left((X_1)_n^{(j)}-\\mathbb{P}_d\\left((X_1)_n^{(j)}\\right)\\right)^\\top\\left((X_2)_n^{(j)}-\\mathbb{P}_d\\left((X_2)_n^{(j)}\\right)\\right)\\end{gathered}$$\n\nThus DCCA generalizes DFA in the sense that if $X_1=X_2$ then $F_{DCCA}^2(n) = F_{DFA}^2(n)$. To simplify the fact that we will need to consider the DFA coefficients of $Y_1$ and $Y_2$ simultaneously, we will also refer to the DCCA coefficients as: $$\\begin{aligned}\n F_{X_1,X_2}^2(n) &:=& F_{DCCA}^2(n)\n \\end{aligned}$$\n\nGiven these definitions, it is possible to show (Proposition\u00a0\\[prop:expectation\\] of the Appendix) that:\n\n1.  If $Y_1(t)$ and $Y_2(t)$ are independent then $\\mathbb{E}(F_{DCCA}^2(n)) = 0$\n\n2.  If $Y_1(t)$ and $Y_2(t)$ are positively correlated, then, on average, and for large window sizes $\\text{log}(F_{DCCA}^2(n))$ is linear against $\\text{log}(n)$\n\n3.  If $Y_1(t)$ and $Y_2(t)$ are negatively correlated, then, on average, and for large window sizes $\\text{log}(-F_{DCCA}^2(n))$ is linear against $\\text{log}(n)$\n\nThis implies that for sufficiently large datasets we should be able to distinguish between those which are power-law cross-correlated and those which are not power-law cross-correlated by checking which of these cases applies; this is also the approach taken in the paper in which DCCA was originally proposed [@DCCA]. Given that we may conclude dependence, we may then further test for power-law correlation by checking whether the absolute value of the slope of $\\text{log}(F_{DCCA}^2(n))$ against $\\text{log}(n)$ is greater than $1/2$. See Figure\u00a0\\[fig:easy\\_examples\\] for two examples of resp.\u00a0independence and dependence for which this method works.\n\n$\\begin{array}{c c c c}\n\\includegraphics[width=40mm,clip=true,trim= 0mm 0mm 8mm 0mm]{easy_examples_UNCORR_LOG_LOG} & \\includegraphics[width=40mm,clip=true,trim=  0mm 0mm 8mm 0mm]{easy_examples_UNCORR_DATA} \\\\\n\\includegraphics[width=40mm,clip=true,trim=  0mm 0mm 8mm 0mm]{easy_examples_CORR_LOG_LOG} & \\includegraphics[width=40mm,clip=true,trim=  0mm 0mm 8mm 0mm]{easy_examples_CORR_DATA} \\end{array}$\n\nIn each case we generate two fractional Gaussian noises[^2], time-series which conform to the model of Equations\u00a0 and\u00a0, with Hurst parameters $0.9$ and $0.7$ respectively and length $20000$ time-points; we choose $n$ to range between $20$ and $2000$. The presence of long-range dependence may be concluded by looking at the slope of $\\text{log}(F_{DFA}^2(n))$ against $\\text{log}(n)$ which is greater than $1/2$ in each case (in red).\n\nIn the first case the time-series are chosen to be independent; here we see that $F^2_{DCCA}(n)$ fluctuates around zero and that no linear dependence of $\\text{log}(F_{DCCA}^2(n))$ against $\\text{log}(n)$ is present. To visualize this we plot $\\text{sign}(|F_{DCCA}^2(n))) \\times \\text{log}(|F_{DCCA}^2(n)|)$ which brings $F^2_{DCCA}(n)$ onto the log scale but allows for inspection of fluctuation around zero. In the second case, the time-series are correlated with correlation equal to $0.4$: we see that $F^2_{DCCA}(n)$ does not fluctuate around zero and that $\\text{log}(F_{DFA}^2(n))$ is linear against $\\text{log}(n)$; the slope of the straight line fit is greater than $1/2$, suggesting the presence of long-range cross-correlation.\n\n### Problems with interpreting the DCCA log-log plot\n\nThus, testing for power-law cross-correlation under this scheme is a *two step* procedure. The second step is formally equivalent to the use of DFA to test for long-range autocorrelation. The *first* step however has no analogy for DFA; indeed it is this first step which is problematic. See Figure\u00a0\\[fig:type\\_I\\_errors\\] for examples of log-log plots for independent fractional Gaussian noises when there is less data available ($N=10000$) and the window sizes $n$ run between $10^1$ and $10^3$. The left hand panel displays $\\text{sign}(|F_{DCCA}^2(n))) \\times \\text{log}(|F_{DCCA}^2(n)|)$ plotted against $\\text{n}$. A straight line is clearly visible, even though the underlying time-series are independent. To demonstrate that such cases are not pathological but occur frequently, we plot, in the right hand panel, the significance level for a $t$-test (two sided test on Pearson\u2019s correlation coefficient at the $p=0.05$ level) for zero correlation as a histogram for 100 simulated fractional Gaussian noises. In 35 cases the null-hypothesis is rejected at the 0.05 significance level: this demonstrates that the statistics for the appearance of a linear relationship in the DCCA log-log plot are quite different to the statistics for standard regressive testing. Thus the presence of a linear relationship between the *empirical* $\\text{log}(F^2_{X_1,X_2}(n))$ and $\\text{log}(n)$ is unreliable as a guide to interaction; in particular, for smaller data sets, where fewer time-scales are available, the presence of an approximately linear relationship may occur spuriously due to the correlations between $F^2_{X_1,X_2}(n_1)$ and $F^2_{X_1,X_2}(n_2)$ for $n_1$ and $n_2$ within a few degrees of magnitude and due to the increasing variance of the $F_{DCCA}^2(n)$ coefficients in $n$. The extra information w.r.t. dependence, omitted by considering the slope, in the case displayed in the left-hand panel of Figure\u00a0\\[fig:type\\_I\\_errors\\], is contained in the *height* of the estimated straight line fit in relation to the DFA straight line fits; compare with the left hand panel of Figure\u00a0\\[fig:easy\\_examples\\]. Thus, the *closer* the DCCA coefficient to the DFA coefficients, the more likely it is that correlation exists between the time-series.\n\n$\\begin{array}{c c}\n\\includegraphics[width=40mm,clip=true,trim= 0mm 0mm 0mm 0mm]{simulating_short_fractional_time_series.pdf}\n& \\includegraphics[width=40mm,clip=true,trim= 0mm 0mm 0mm 0mm]{p_values_standard_vs_revised.pdf}\\end{array}$\n\n### The DCCA correlation coefficients and statistical testing {#sec:DCCA_testing}\n\nIn accordance with the observation that the *magnitude* of the $F_{DCCA}^2$ coefficients carry information relating to the strength of dependencies, Podobnik et al. study, in a later paper \u00a0[@podobnik2011statistical], the *DCCA correlation coefficient*, initially introduced by [@zebende2011study]: $$\\rho_{DCCA}(n,X_1,X_2) = \\frac{F^2_{X_1,X_2}(n)}{\\sqrt{F^2_{X_1,X_1}(n)}\\sqrt{F^2_{X_2,X_2}(n)}} \\label{eq:rho}$$\n\nThe coefficient is analogous to Pearson\u2019s correlation coefficient, in that the terms on the denominator are the detrended *variances* which are utilized in DFA and the numerator DCCA coefficient is a detrended *cross-covariance*; moreover, as for Pearson\u2019s coefficient, $\\rho_{DCCA}$ may be shown to lie between $-1$ and $1$ [@podobnik2011statistical] and thus presents a promising starting point in testing for long-range interdependence.\n\nHowever, testing with $\\rho_{DCCA}$ is a very different problem to testing with a standard correlation coefficient: the distributional theory which applies to the standard coefficient does not apply here on account of the detrending. In accordance with this fact Podobnik et al.\u00a0propose to construct a test for power-law cross-correlation by estimating the quantiles of $\\rho_{DCCA}(n,X_1,X_2)$ using a FARIMA assumption and comprehensive computer simulation of time-series of the same length as the empirical time-series. In doing so they provide a guide to interpreting the significance of observing a particular value of $\\rho_{DCCA}(n,X_1,X_2)$ on a given data set by providing insight into the range of $\\rho_{DCCA}$ values which may arise under the null hypothesis of independence due to small sample fluctuations. See Figure\u00a0\\[fig:rho\\_test\\], which displays empirical DCCA correlation coefficients and the critical level $\\rho_c$ for each coefficient for a power-law correlated time-series ($\\rho = 0.3$- fractional Gaussian noise) and an uncorrelated case ($\\rho = 0$): we see that for the uncorrelated case, all DCCA correlation coefficients lie between the 0.05 level critical boundaries, whereas, in the correlated case, all DCCA correlation coefficients lie above the upper boundary (denoting positive correlation).\n\nThis proposal does not consider, however the complications induced by the fact that one obtains *several* $\\rho_{DCCA}$ coefficients for every data set considered, depending on the number of scales considered. The first difficulty this generates is that since we are faced with multiple DCCA correlation coefficients, simply checking whether any of the coefficients lie above the critical level is susceptible to multiple testing errors; when many coefficients are measured, random fluctuations under the null hypothesis will more probably drive at least one empirical coefficient into the critical region. The standard technique for dealing with this issue is to perform a simple multiple testing-correction; one would then report long-range dependence when at least one coefficient is measured as significant after this correction.\n\nTesting the individual scales separately and then correcting, however, is at odds with the fact that long-range dependence is a *broadband* phenomenon; thus information relating to long-range temporal dependence should be visible *across* time-scales, not simply in one scale displaying highly significant results. Moreover, since the effective sample size generating the coefficients at small scales is greater than at large scales, the coefficients at small scales will display significant readouts even under spurious and weak short-range dependence but long-range independence. Using a multiple testing-correction in such cases will results in a fallacious rejection of the null-hypothesis of long-range independence. Thus since the coefficients at small scales are highly sensitive to short range cross-correlation properties, a multiple testing correction won\u2019t succeed in controlling the Type I error rate in cases in which the short range properties of the true distribution differ from its long-range properties. See, the right hand panel Figure\u00a0\\[fig:rho\\_test\\] for a case in which the multiple testing correction leads us astray.\n\n$\\begin{array}{c c}\n\\includegraphics[width=40mm,clip=true,trim= 0mm 0mm 0mm 0mm]{rho_test_ILLUSTRATION.pdf} & \n\\includegraphics[width=40mm,clip=true,trim= 0mm 0mm 0mm 0mm]{rho_test_ILLUSTRATION_SPURIOUS.pdf}\n\\end{array}$\n\nThe blue points display the $\\rho_{DCCA}$ values of two long-range dependent time-series; all points lie above the given critical threshhold. The green points, however display the $\\rho_{DCCA}$ coefficients of a bivariate time-series simulated as a superposition of two independent long-range dependent fractional Gaussian noises and *correlated* Gaussian white noises. Thus the time-series are long-range *independent* but short-range *dependent*. Since we are interested in long-range properties, it is desirable that the testing-procedure should be made robust to these short-range correlation properties. In Figure\u00a0\\[fig:rho\\_test\\] we see that the DCCA correlation coefficients (green) exceed the critical boundaries at small scales, due to short range dependence but not at large scales due to long-range independence. This implies that a test based simply on performing a multiple testing-correction will lead to erroneous rejection of the null-hypothesis when the short-range component of the time-series contains correlations.\n\n### Proposed Solutions\n\nThe alternative which we propose in this paper involves calculating the probability that *all* DCCA correlation coefficients exceed a certain level *simultaneously*. See the right hand panel of Figure\u00a0\\[fig:rho\\_test\\] for an illustration of this procedure. Under the null hypothesis of long-range independence but with short range dependence, the DCCA correlation coefficients at small scales lie far above the significance level corrected for multiple comparisons (red). On the other hand, at higher scales, coefficients behave similarly to the coefficients of fractional Gaussian noise and thus the null hypothesis is not rejected using the proposed method based on requiring that *all* coefficients lie above the upper turquoise boundary. Thus, critically, the procedure we propose requires using the *full* distribution of the $\\rho_{DCCA}$ coefficients across scales.\n\nAn immediate question which arises is: what if the opposite situation applies to that illustrated by the right hand panel of Figure\u00a0\\[fig:rho\\_test\\]? I.e.: the pair of time-series are long-range dependent but no correlation is present in the short range component. This will imply that the $\\rho_{DCCA}$ coefficients will point to dependence at large scales but not at small scales. Thus there may be no critical line above which all coefficients probably lie in the case of dependence. We show in Section\u00a0\\[sec:method\\], that the information in the joint distribution of the $\\rho_{DCCA}$ coefficients may be used to cater to this case while remaining robust to spurious short-range correlations.\n\nOnce the decision has been made to use the joint distribution of the $\\rho_{DCCA}$ coefficients then we need to ask: how should the distribution of the $\\rho_{DCCA}$ coefficients be calculated in practice? Derivation of a closed form solution of the exact probability density function even for a parametric family of Gaussian process time-series presents a formidable task of analysis due to the high dimensionality of the probability space and the detrending operation which is implicit in calculation of the coefficients. In the parametric setting, Podobik et al.\u00a0[@podobnik2011statistical] resort to estimation via simulated surrogate data for estimation of the distribution of a single $\\rho_{DCCA}$ coefficient. On the basis of these calculations, the authors conjecture that the coefficients are asymptotically normal; however, since no expression is given for the parameters of this normal limit, nor an analysis of the convergence rate, simulated data is still required for its calculation. This approach may be in principle extended to estimation of the joint distribution of the $\\rho_{DCCA}$ coefficients, however, for long time-series the ansatz is computationally inefficient. For example for estimation of 10,000 time-series, when $N=80,000$, which is approximately the number required in order to estimate the type I error distribution in a stable manner, we estimate on a standard desktop system that approximately $28$ hours of computation is necessary. On the other hand, in cases when the ansatz *is* efficient, empirical data is often insufficient to reliably estimate long-range properties of the data; thus cases in which the time-series considered are short are of less practical interest.\n\nQuite apart from these computational difficulties, since we specify the model of interest in a semi-parametric fashion as per Equations\u00a0 and\u00a0 there is no guarantee that simulation from a parametric model will yield accurate results in approximating the true distribution of the $\\rho_{DCCA}$ coefficients. This approach may only be regarded as valid if we may relate the parametric class chosen on the one hand to behaviour across the semi-parametric class on the other; typically this will be effected by means of asymptotic analysis [@DFA_asymp; @moulines2007spectral]. However, given precise asymptotic estimates across the semi-parametric class, the simulation technique is no longer necessary and the estimates may be used directly. We show in this paper in theory and simulation that there exists a central limit to which the $\\rho_{DCCA}$ coefficients converge which is universal with respect to a broad delineation of the semi-parametric class of interest of Equations\u00a0 and\u00a0. In addition we show that this limit yields an efficient approach to estimation of the distribution of the $\\rho_{DCCA}$ coefficients under the null hypothesis.\n\nMethod {#sec:method}\n======\n\nThe technical details of our method are catalogued in Algorithm\u00a0\\[alg:test\\]. Here we provide an informal description and explanation of the major steps involved.\n\nOur method consists of two steps: firstly we use theoretical results to calculate an approximation to the distribution of the $\\rho_{DCCA}$ coefficients under the null hypothesis of independence. Secondly we construct a test-statistic and rejection region which incorporate on the one hand the fact that the Hurst exponents of the two time-series are known only approximately through estimation and on the other hand assumptions as to the orders of magnitude over which scaling is expected under the alternative hypothesis of power-law cross-correlation.\n\nThe asymptotic distribution of the DCCA correlation coefficients\n----------------------------------------------------------------\n\nWe showed in the previous section that it is desirable to use the *joint* distribution of the $\\rho_{DCCA}$ coefficients in order to judge long-range dependence. The aim of this section is to describe the theory which allows us to estimate the probability that $\\rho_{DCCA}(n_1)>a_1 \\& \\dots \\& \\rho_{DCCA}(n_r)>a_r$ for some choice of $a_1, \\dots, a_r$ under the null-hypothesis of long-range independence and the steps required in practice for execution of this estimation.\n\nTo recap the first step in any DCCA analysis is to form: $$X_j(t) = \\sum_{i=1}^t Y_j(i) \\label{eq:subsample}$$\n\nBecause $X_j(t)$ involves a sum over samples, as $t$ grows, the distribution of $X_j(t)$ may be shown, under certain assumptions, to converge at low frequencies to a specific class of Gaussian process, namely *fractional Brownian motion* (see [@taqqu1975weak] and Proposition\u00a0\\[prop:Taqqu\\]). This may moreover be shown to be true for the *joint* distribution of $X_1(t)$ and $X_2(t)$, which may be shown to converge to a bivariate fractional Brownian motion [@marinucci2000weak]. An implication of this convergence which may be shown in simulations and in theory (Proposition\u00a0\\[prop:non\\_gauss\\]) is that the distribution of the DFA and DCCA coefficients of the two time-series converge, at large scales, to the distribution of the DFA and DCCA coefficients of a bivariate fractional Brownian motion (resp. bivariate fractional Gaussian noise). Thus if we succeed in calculating the distribution of the DFA and DCCA coefficients of a bivariate fractional Brownian motion, then these will approximate the distribution of the coefficients of a broad class of long-range dependent time-series.\n\nThus the next step is to consider the distribution of the DFA and DCCA coefficients specifically for fractional Gaussian noise time-series. The asymptotics of the DFA coefficients in this context have already been studied by [@DFA_asymp]. In particular, the authors of [@DFA_asymp] show that as $[N/n_r] \\rightarrow \\infty$ then the DFA coefficients of a fractional Brownian motion are normally distributed. We extend this work by showing that this limit generalizes to the DCCA coefficients under the null hypothesis of independence (Proposition\u00a0\\[prop:semi\\]). Thus as $[N/n_r] \\rightarrow \\infty$ the DCCA coefficients are normally distributed, assuming independence. These two asymptotic analyses imply that the $\\rho_{DCCA}$ coefficients of a bivariate fractional Gaussian noise are *also* asymptotically normal (Proposition\u00a0\\[prop:CLT\\]). The covariance matrix of the normal limit may be exactly calculated using the covariance and means of the DFA and DCCA normal limits and these moments may themselves be approximated in a tractable and accurate manner. The convergence rate is the following:\n\n$$\\left(\\sqrt{N/n_1})\\rho_{DCCA}(n_1),\\dots, \\sqrt{N/n_r}\\rho_{DCCA}(n_r)\\right) \\rightarrow \\mathcal{N}(0, \\Theta(H,G)) \\label{eq:central_limit}$$\n\nThus we obtain an approximation to the distribution of the $\\rho_{DCCA}$ coefficients of a bivariate fractional Gaussian noise; in virtue of the fact that the DCCA coefficients tend in distribution to the DCCA coefficients of fractional Gaussian noise at large scales, this central limit is thus also an approximation to the distribution of the $\\rho_{DCCA}$ coefficients of $Y_1$ and $Y_2$ across the semi-parametric class for large scales (Proposition\u00a0\\[prop:glue\\]). The accuracy of this approximation may be shown in simulations to be sufficient to be *useful* in practice (see Sections\u00a0\\[sec:check\\_fGn\\],\u00a0\\[sec:check\\_non\\_gauss\\] and\u00a0\\[sec:check\\_spurious\\]). So given that we have access to $H$ and $G$, we may calculate the probability under the null hypothesis that $\\rho_{DCCA}(n_1)>a_1 \\& \\dots \\& \\rho_{DCCA}(n_r)>a_r$.\n\nUpper bounding the quantiles of the distribution of the DCCA correlation coefficients\n-------------------------------------------------------------------------------------\n\nWe now deal with the question: what if $H$ and $G$ are known only approximately through estimation? The solution we provide is to calculate a covariance matrix $C$ so that if $0.5\\leq H,G<1$ then asymptotically:\n\n$$\\begin{aligned}\n&& \\text{Pr}(\\rho_{DCCA}(n_1)>a_1 \\& \\dots \\& \\rho_{DCCA}(n_r)>a_r) \\\\\n&<& \\text{Pr}(x_1>a_1 \\& \\dots \\& x_r>a_r | (x_1,\\dots,x_r) \\sim \\mathcal{N}(0,C)) \\label{eq:upper_bound}\n\\label{eq:upper_bound}\\end{aligned}$$\n\n$C$ is calculated by choosing the correlations between dimensions to be identical to the maximum correlations between $\\rho_{DCCA}$ coefficients considering $H$ and $G$ in this range and the diagonal entries are chosen so that these are equal to the maximum variances for this range. This choice then yields Equation\u00a0 in the asymptotic regime. Given that more exact information as to the magnitude of the true $H$ and $G$ is available, $C$ may be recalculated to yield a more powerful test.\n\nThe test-statistic and rejection region\n---------------------------------------\n\nThe test-statistic is defined as follows. If $H$ and $G$ are known exactly then $C$ is given by the limiting covariance of the central limit approximation of Equation\u00a0. Otherwise, $C$ is calculated according to Equation\u00a0. Then, for a fixed $\\kappa$:\n\n$$\\begin{gathered}\n\\mathcal{T}_\\kappa =  \\text{max}_{\\lambda>0}( \\exists n_{r_1} , \\dots, n_{r_\\kappa}| \\\\ \\rho_{DCCA}(n_{r_1}) > \\lambda \\sqrt(C_{r_1,r_1}),\\dots, \\rho_{DCCA}(n_{r_\\kappa}) > \\lambda \\sqrt(C_{r_{\\kappa},r_{\\kappa}}) \\\\\n\\text{ or } \\\\ -\\rho_{DCCA}(n_{r_1}) > \\lambda \\sqrt(C_{r_1,r_1}),\\dots, -\\rho_{DCCA}(n_{r_\\kappa}) > \\lambda \\sqrt(C_{r_{\\kappa},r_{\\kappa}}))\\end{gathered}$$\n\nThe parameter $\\kappa$ is included because we wish to be able to reject the null-hypothesis of no power-law cross-correlation even if a few of the $\\rho_{DCCA}$ coefficients display no correlation. Thus the test-statistic incorporates two important aspects: firstly the joint distribution is used ensuring robustness to short range correlations, provided $\\kappa$ is close to $r$. Secondly, by choosing $\\kappa$ to be close to $r$ but not equal to $r$, we include the possibility that, certain scales are either contaminated by confounding noise and thus display *no* correlation or that long-range cross-correlation is only visible over the largest scales; see the discussion and conclusion section for more on these possibilities (e.g. the delta rhythm in fMRI research and the slow onset of power-law cross-correlation in EEG amplitude time series).\n\nThe final step in defining the test involves choosing $\\kappa$ and choosing a rejection region for $\\mathcal{T}_\\kappa$ for a given level $p_{level}$, i.e. we require $\\phi$ s.t.:\n\n$$\\text{Pr}(|\\mathcal{T}_{\\kappa}| > \\phi\\text{ } | \\text{ }\\mathcal{H}_0) \\leq p_{level}$$\n\nThis may be achieved as follows: if $\\kappa = r$ the solution is simple, one uses simply the distribution of $\\mathcal{N}(0,C)$. If, however, $\\kappa< r$, then we have the following inequality, assuming that $n_1,\\dots,n_r$ are evenly log-spaced then asymptotically (for large $n_i$ and $N/n_i$):\n\n$$\\begin{gathered}\n\\text{Pr}\\left(\\rho_{DCCA}(n_{r_1}) > \\lambda \\sqrt(C_{r_1,r_1}),\\dots, \\rho_{DCCA}(n_{r_\\kappa}) > \\lambda \\sqrt(C_{r_{\\kappa},r_{\\kappa}} \\right)\n\\\\ \\leq \\text{Pr}\\left(\\rho_{DCCA}(n_{1}) > \\lambda \\sqrt(C_{1,1}),\\dots, \\rho_{DCCA}(n_{\\kappa}) > \\lambda \\sqrt(C_{{\\kappa},{\\kappa}} \\right)\\end{gathered}$$ Thus: $$\\begin{gathered}\n\\text{Pr}(|\\mathcal{T}_{\\kappa}| > \\phi \\text{ } | \\text{ } \\mathcal{H}_0 ) \\\\\n< 2 \\begin{pmatrix}r \\\\ \\kappa \\end{pmatrix} \\text{ } \\text{Pr}\\left(\\rho_{DCCA}(n_{1}) > \\phi \\sqrt(C_{1,1}),\\dots, \\rho_{DCCA}(n_{\\kappa}) > \\phi \\sqrt(C_{{\\kappa},{\\kappa}}) \\right)\\end{gathered}$$ The test procedure is implemented in software (described in Section\u00a0\\[sec:software\\] of the Appendix) which is available for download[^3]. A final question which may arise is the following: why does rejection of the test imply long-range cross-correlation and not simply cross-correlation? The answer is that it is possible to show that the bivariate time-series $(X_1(t),X_2(t))^\\top$ has asymptotic properties identical to those of a bivariate fractional Brownian motion sharing the Hurst exponents of each of the components [@marinucci2000weak]. This implies that the exponent of cross-correlation (Equation\u00a0) is long-range if one of $H$ and $G$ is greater than $1/2$, since if fractional Gaussian noises are correlated then they are power-law correlated provided $H,G \\geq 1/2$ and one of $H$ and $G$ is $>1/2$ [@SimulatorVfbm]. This implies that if the time-series are short-range cross correlated but not long-range cross-correlated, then the approximating fBm will possess independent components and for large enough scales the hypothesis of no long-range cross correlation will not be rejected.\n\nSimulations\n===========\n\nIn this section we present simulations which check the proposed method for correctness, power and efficiency. The first two simulations (Sections\u00a0\\[sec:check\\_fGn\\],\u00a0\\[sec:check\\_non\\_gauss\\]) check the accuracy of the approximation provided by the central limit theorem (Equation\u00a0); the third (Section\u00a0\\[sec:check\\_spurious\\]) checks the robustness of the test-statistic to spurious short-range correlations; the fourth (Section\u00a0\\[sec:check\\_ub\\]) checks the upper bound of Equation\u00a0; the fifth checks the power of the test as a function of the correlation between the components of a bivariate fractional Gaussian noise; the final Simulation (Section\u00a0\\[sec:check\\_speed\\]) checks the computational efficiency of the proposed test.\n\nChecking the distribution of the test-statistics for fractional Gaussian noise {#sec:check_fGn}\n------------------------------------------------------------------------------\n\nSince our test is based on approximating the distribution of the test-statistics under the null by means of the asymptotics for fractional Gaussian noise, we first check the approximation when the time-series are fractional Gaussian noises. Thus in the case in which $H$ and $G$ are known exactly and in the case in which $\\kappa = r$, the central limit approximation should become exact for fractional Gaussian noise in the limit of data points and window sizes (see the Appendix). In each case we use the fractional Gaussian noise generation method of [@SimulatorVfbm] to generate $100,000$ bivariate fractional Gaussian noises with $H=0.7, G=0.8$. We first check the approximation in the body of the support of the test-statistic for two values of $r$ (number of time-scales on which the $\\rho_{DCCA}$ coefficient is calculated). The results of these two experiments are displayed in the first row of Figure\u00a0\\[fig:bootstrp\\_confidence\\_theory\\_practice\\]; comparing the top-left panel with the top-right panel, we see that for larger window sizes, the approximation is of higher quality but in both cases an approximation to within 0.005 of the target probability is achieved. The increase in accuracy for higher window sizes relates not to convergence to normality but to the approximation of the covariance matrix via tabulation, which is more accurate for larger window sizes.\n\nWe then investigate two cases in the tails of the distribution of the test-statistic, which are of more relevance in testing, since a typical test requires control of the Type I error rate to values of at most 0.05. Thus on the second row of Figure \u00a0\\[fig:bootstrp\\_confidence\\_theory\\_practice\\] we see displayed two cases in which the target quantile is of probability approximately 0.03: the first case involves fewer window sizes than the second case. Both results of these latter two simulations show that the central limit approximation converges more slowly at the tails of the distribution of the test-statistic than in the body of the support, although agreement is more than adequate to guarantee usefulness in practice. In all cases the results are robust to the exact choice of parameter values, $G$ and $H$, and the quality of the approximations made increase in $[N/n_i]$ (where the $n_i$ are the window sizes). Because we use a detrending operation, the results are robust to polynomial trends of degree $d$ in $X_1(t)$ and $X_2(t)$. All simulations cited here set the detrending degree to $d=1$, however additional simulations (not presented here) confirm that the results generalize to higher order detrending.\n\n$\\begin{array}{c c }\n\\includegraphics[width=40mm]{null_test_HIGHER_N.pdf} &\n\\includegraphics[width=40mm]{null_test_HIGHER_N_HIGHER_n.pdf}  \\\\\n\\includegraphics[width=40mm]{null_test_RHO_DEGREE_1.pdf} &\n \\includegraphics[width=40mm]{null_test_HIGHER_N_MEDIUM_PROB.pdf}\n\\end{array}$\n\nChecking the distribution of the test-statistic for non-Gaussian processes {#sec:check_non_gauss}\n--------------------------------------------------------------------------\n\nThe second simulation checks the quality of the approximation (Equation\u00a0) for non-Gaussian data and compares the results to the results for Gaussian data. In order to generate an appropriate non-Gaussian time-series we use the result of the paper [@blum1994simple]; here it is shown that a non-Gaussian fractional noise may be generated by appropriately filtering a non-Gaussian white noise. Accordingly we generate a super-Gaussian white noise ($x_{nonGaussian} = \\text{sign}(x_{Gaussian})\\times|x_{Gaussian}|^\\phi$) for $\\phi=3$ and filter according to the procedure proposed by [@blum1994simple]. The resulting time-series is thus a linear time-series sharing the second-order statistics of fractional-Gaussian noise but differing in its higher order-statistics (see the right panel of Figure for an illustration of the data).\n\nThe 0.05 level calculated on 10,000 samples of this non-Gaussian fractional noise with $N=5000,10000,20000,40000$ and $G=0.7,H=0.8$ is compared with the 0.05 level calculated on simulated fractional Gaussian noises and the level generated by the proposed method. The results displayed in Figure\u00a0\\[fig:null\\_test\\_non\\_gaussian\\] show that the accuracy of the theoretical approximation is similar for non-Gaussian fractional noise and Gaussian fractional noise. This may be related to the fact that the second-order statistics of both processes are similar, and, under the null-hypothesis the covariance matrix which we calculate for the $\\rho_{DCCA}$ coefficients depends only on the second-order statistics of the two processes considered; see Equation\u00a0 of the Appendix.\n\n$\\begin{array}{c c}\n\\includegraphics[width=40mm,clip=true,trim= 5mm 0mm 2mm 0mm]{null_test_non_gaussian.pdf} & \\includegraphics[width=40mm,clip=true,trim= 5mm 0mm 2mm 0mm]{null_test_non_gaussian_HIST.pdf}\n\\end{array}$\n\nChecking the distribution of the test-statistic for Gaussian time-series with a correlated short-range component {#sec:check_spurious}\n----------------------------------------------------------------------------------------------------------------\n\nThe third simulation checks the robustness of control over the type I error rate for the proposed method in the presence of a spurious short-range correlated component and compares against a multiple testing-correction. Although choosing large enough scales reduces the effect of these short-range correlations on the distribution of the $\\rho_{DCCA}$ coefficients, exactly at what magnitude the smallest scale should be chosen in practice is unclear. In this simulation we investigate a case in which the short-range correlations in the time-series exert influence over the distribution of the $\\rho_{DCCA}$ coefficients at small scales and evaluate the on the distribution of our test-statistic; thus although for increasingly larger windows sizes Propositions\u00a0\\[prop:non\\_gauss\\] and\u00a0\\[prop:glue\\] guarantee that the central limit theorem provides a more accurate approximation, in the finite window size regime the approximation is coarser. We compare the probability of Type I error for the test proposed above using the exact asymptotics of $\\mathcal{T}_r$ and the multiple testing procedure discussed in Section\u00a0\\[sec:DCCA\\_testing\\] with the test-level set for both procedures to 0.05. (Thus the multiple testing procedure uses the *univariate* asymptotics of the DCCA coefficients and reports LRCC if at least one of the coefficients delivers a significant readout after a Bonferroni multiple comparisons correction.) In particular, we simulate 10,000 bivariate time-series which are generated as a linear superposition of a bivariate fractional Gaussian noise with $H=G=0.9$ and a correlated Gaussian White Noise, high pass-filtered to the frequencies above 0.45 times its sampling frequency. This simulation is repeated for 4 log-spaced choices of $N = 5000,10000,20000,40000$ and the probability of rejection at the 0.05 null hypothesis level, calculated using the proposed method compared with the probability of rejection at the 0.05 null hypothesis using the multiple testing correction method.\n\nThe results are displayed in Figure\u00a0\\[fig:slowly\\_varying\\] and show that while the proposed method slightly underestimates the Type I error rate at the 0.05 level ($\\approx 0.06$), the multiple testing correction grossly underestimates the Type I error rate. Moreover, while the underestimation becomes all the more drastic with increasing $N$ in the case of the multiple testing correction, the proposed method continues to estimate stably. The reason for this difference is that for the proposed method, the $\\rho_{DCCA}$ coefficients at the lowest scales can never be solely responsible for a rejection of the null-hypothesis: *all* (or most if $\\kappa \\neq r$) coefficients must display information regarding correlation. On the other hand, since the short-range correlation measured in the $\\rho_{DCCA}$ coefficients at small scales is measured as significant in these small-scales more often when $N$ is larger (larger sample size), the underestimation of the type I error rate grows in $N$ for the multiple testing procedure.\n\n$\\begin{array}{c c}\n\\includegraphics[width=40mm,clip=true,trim= 0mm 0mm 5mm 0mm]{slowly_varying.pdf} & \\includegraphics[width=40mm,clip=true,trim= 0mm 0mm 5mm 0mm]{slowly_varying_SCATTER.pdf}\n\\end{array}$\n\nChecking the upper bound for the cases in which the Hurst exponents are estimated {#sec:check_ub}\n---------------------------------------------------------------------------------\n\nThe fourth simulation checks that the bound we present in Equation\u00a0 may be used to correctly upper bound the probability of a Type I error when $H$ and $G$ are unknown or known only approximately through estimation. To this end we calculate the rejection boundary according to the proposed method when $H$ and $G$ are known, for $H,G$ in the range $[1/2,1)$, using the central limit theorem and calculation of the limiting covariance matrix and the rejection boundary using the worst case covariance matrix. The rejection boundaries when $H$ and $G$ are known are plotted in Figure\u00a0\\[fig:check\\_upper\\_bound\\] in blue and the rejection boundary using the worst case upper bound is plotted in red. The results confirm that the worst case boundary correctly lies above the boundaries when $H$ and $G$ are known, for all values of $H$ and $G$.\n\n![Correctness of the $p$-values when $H$ and $G$ are unknown; the figure displays the upper bound rejection line (red) of Equation\u00a0 in comparison to the rejection lines generated by the central limit theorem when $H$ and $G$ are known (blue). Thus when *all* $\\rho_{DCCA}$ coefficients lie above the rejection lines, the null is rejected. The fact that the red rejection line lies above every blue rejection line confirms that the upper bound of Equation\u00a0 allows for strict control over the type I error rate despite access to $H$ and $G$ only through estimation. \\[fig:check\\_upper\\_bound\\]](check_upper_bound.pdf){width=\"60mm\"}\n\nChecking the test is useful by checking test power\n--------------------------------------------------\n\nThe penultimate simulation tests the power of the test we present when the type I error rate is controlled at the 0.05 level. Thus we check that the test may be effectively used to reject the null in cases of dependence by generating 330 time-series for varying levels of long-range cross-correlation $\\rho \\in [0.005,0.2]$, $N=40000$, $H,G = 0.7,0.8$. The results are displayed in Figure\u00a0\\[fig:power\\_function\\] and show that the null-hypothesis is rejected in more than 50 percent of cases when $\\rho > 0.07$. Although this shows that the proposed method results in less frequent rejection of the null than in a standard correlation analysis (not taking long-range dependence into account), the power is sufficient for detection of weak long-range correlation when $N \\geq 40000$ and possesses the advantages of robustness to polynomial trends and to the presence of confounding short-range correlations.\n\n![Test power of the proposed method; the figure displays the test power plotted as a function of the correlation parameter $\\rho$ of the bivariate fractional Gaussian noises which are generated. The errorbars are calculated using bootstrapped means after simulation of 330 time-series for each value of $\\rho$. The results show that for values of $\\rho \\geq 0.07$, the null-hypothesis is rejected at the 0.05 level in over 50% of cases. \\[fig:power\\_function\\]](power_function.pdf){width=\"80mm\"}\n\nChecking the test is useful in terms of computational efficiency {#sec:check_speed}\n----------------------------------------------------------------\n\nFinally we investigate the speed of the proposed method in comparison to computation of the test-distribution via simulated data as per [@podobnik2011statistical]. Here we estimate in simulation the amount of time necessary for stable estimation of the 0.05 quantiles of the test distributions, given that $H$ and $G$ are known using the proposed method and simulation using a fractional Gaussian noise generator. Podobnik et al.\u00a0require 10,000 samples for this calculation in simulation. Thus in Figure\u00a0\\[fig:speed\\] we display the amount of computation time required for the proposed method and the simulation method. The results show that the proposed method is over 5 orders of magnitude faster than the method of simulation. Although the proposed method involves sampling Gaussian data in order to evaluate the quantiles of the central limit, the simulation shows that drawing these samples requires considerably less computation time than drawing samples explicitly from a fractional Gaussian noise simulator.\n\n![Speed-up the proposed method over simulation of surrogate data; the respective values display the estimated time required for estimation of the distribution of the $\\rho_{DCCA}$ coefficients for a time-series of length $N = 80,000$. \\[fig:speed\\]](speed.pdf){width=\"60mm\"}\n\nConclusion\n==========\n\nThis paper has detailed a test for power-law cross-correlated behaviour which incorporates information across time scales, may be executed efficiently without extensive simulation and has been shown to be robust to a range of distributional assumptions. Thus for applications where interactions are weak we may rigorously check the significance of the observed $\\rho_{DCCA}$ coefficients across time-scales. Moreover, because the derivations are based on the $\\rho_{DCCA}$ coefficients, the method inherits the advantages possessed by DCCA, i.e. robustness to polynomial trends of a predetermined degree.\n\nFurther work will involve broader application of the test in physics, geophysics, biomedical fields and neuroscience, extension of the theory to cover a broader semi-parametric class, for example incorporating the assumption of non-linearity, investigation of alternative modes of detrending and the development of efficient numerical methods for calculation of the limiting covariance matrix.\n\nAcknowledgements\n================\n\nThe author would like to thank Daniel Bartz for his comments and suggestions on the topic of this paper and Prof. Klaus-Robert M\u00fcller for valuable advice and support.

This formulation allows for non-Gaussianity, for confounding non-stationarities and for the presence of a high frequency component of the power-spectrum differing at those high frequencies from a power law[^5]; this formulation formalizes the formulation of Equations\u00a0 and\u00a0 of the main body of the paper. We believe that the class of functions we consider is, moreover, more restrictive than necessary and conjecture that the requirement of linearity may be replaced by a constrained non-linearity assumption.\n\nGiven this formulation, in the following, we lever existing theoretical work and use the covariance function of fractional Brownian motion in order to construct a test valid for this semi-parametric class (see Section\u00a0\\[sec:theory\\]). The covariance function of multivariate fractional Brownian motion is given as follows; if $X_1(t)$ and $X_2(t)$ are two components of the multivariate fractional Brownian motion, then:\n\n1.  If $H + G \\neq 1$ $$\\begin{aligned}\n    \\mathbb{E}(X_1(s)X_2(t)) &=& \\frac{\\sigma_1\\sigma_2}{2} \\bigg((\\rho + \\eta \\text{sign}(s))|s|^{H+G} + (\\rho - \\eta \\text{sign}(t) )|t|^{H + G} -  (\\rho - \\eta \\text{sign}(t-s)) |t-s|^{H + G}\\bigg) \\label{eq:cov}\\end{aligned}$$\n\n2.

Under certain regularity conditions Lavancier et al.\u00a0[@LavCov] are able to show that this covariance function moreover applies to any $L^2$ self-similar multivariate process with stationary increments.\n\nMethod details\n==============\n\nAlgorithm\u00a0\\[alg:test\\] formalizes the proposed test procedure; subroutines are stated explicitly in Algorithms\u00a0\\[alg:wccov\\] and\u00a0\\[alg:critical\\_region\\] respectively.\n\n$C_{i,i} = \\text{max}_{H \\in [H_{low},H_{high}], G \\in [G_{low},G_{high}]} \\text{var}(\\rho_{DCCA}(n_i,X_G,X_H))$ $r_{i,j} = \\text{max}_{H \\in [H_{low},H_{high}], G \\in [G_{low},G_{high}]} \\times \\newline\\hspace{1in} \\text{corr}(\\rho_{DCCA}(n_i,X_G,X_H),\\rho_{DCCA}(n_j,X_G,X_H))$ $C_{i,j} = r_{i,j} \\sqrt{C_{i,i}} \\sqrt{C_{j,j}} $ $C$\n\n$a_i(\\theta) = \\theta  \\sqrt{C_{i,i}}$ $A(\\theta)$ = $\\{ (x_1,\\dots,x_r) | x_{r_1} >a_{r_1}(\\theta),\\dots,x_{r_{\\kappa}} > a_{r_\\kappa}(\\theta) \\text{ or } -x_{r_1} >a_{r_1}(\\theta),\\dots,-x_{r_{\\kappa}} > a_{r_\\kappa}(\\theta) (\\text{some } r_1, \\dots) \\}$. $A = A(\\theta^*)$ s.t. $\\theta^* = \\text{min}_\\theta\\left(Pr_{\\mathcal{N}(0,C)}((x_1,...,x_r) \\in A(\\theta)) < p\\right)$. $A$\n\nCompute $X_1$ and $X_2$ by $X_1(t) =  \\sum_{j=1}^{t} Y_1(j)$ and $X_2(t) =  \\sum_{j=1}^{t} Y_2(j)$ Split $X_1$ and $X_2$ into windows of length $n_i$: $X_{j,n_i}^{1},\\dots X_{j,n_i}^{[N/n_i]}$ and Calculate the degree $d$ polynomial trend in each window to yield $\\widehat{X}_{j,n_i}^{1},\\dots \\widehat{X}_{j,n_i}^{[N/n_i]}$.

Numerical calculation of this integral is inefficient and inaccurate when $r$ is large. In such cases, it is more straightforward and more efficient to estimate the relevant probabilities using a Gaussian random number generator[^6]. Notice that this is a considerably more compact computation than the computation undertaken by Podobnik et al. [@podobnik2011statistical]. When $r=25$, $10^6$ samples suffice to obtain a stable estimate for a case in which the corresponding probability is $\\approx 0.0510$ to within a tolerance of $\\pm 0.001$ which takes approximately $2.4$ seconds in MATLAB. The efficiency in estimation is due to the high correlations between the DCCA coefficients across scales, which reduces the effective dimensionality of the support of the distribution.\n\n### Calculating asymptotic covariance\n\nWe calculate the variance of the $F_{X_1,X_2}^2(n)$ by evaluating, for $H,G = 0.5,0.52,\\dots,0.96,0.98$ an exact formula (Equation\u00a0\\[eq:covariance\\_fun\\]) for large but computationally feasible $N$ and $n$. We then calculate $[N/n]$ times this variance which should correspond up to finite sample error to the asymptotic limit posited by the theory (below). Then for a new $N'$ and $n'$ the required variance is approximately $1/[N'/n']$ times this limit.\n\nMoreover, in order to calculate the cross terms we tabulate the correlation between $F_{X_1,X_2}^2(n), F_{X_1,X_2}^2(n')$ for $H,G = 0.5,0.52,\\dots,0.96,0.98$ and for feasible $N$ and $n$ and $n'=0.01\\times n,  \\dots, 0.98 \\times n, 0.99 \\times n$. For $n' < 0.01 \\times n$ the correlation is approximately zero but is upper bounded by the correlation when $n'=0.01$, to be conservative. The covariance term of $F^2(n)$ is then calculated from the variance and correlation terms.\n\nFinally we require the mean of the $F^2_{X_1,X_1}(n)$ terms. For polynomial trending of degree one this mean is given analytically (see ref. [@DFA_asymp], Property 3.1). Otherwise the mean may be calculated in a similar manner to the calculation of covariance.

The extension to higher order detrending ($d>1$) is straightforward. When $H=G$, then we have: $$\\text{cov}(F^2_{1,X_1,X_2}(n),F^2_{j,X_1,X_2}(m)) =  \\text{trace}(Q_d \\Sigma_H Q_d \\Sigma_H^\\top)$$ But $\\text{trace}(Q_d \\Sigma_H Q_d \\Sigma_H^\\top) < \\text{trace}(Q_1 \\Sigma_H Q_1 \\Sigma_H^\\top)$, since $\\text{trace}(Q_d \\Sigma_H Q_d \\Sigma_H^\\top)$ is the Froebenius norm of $Q_d \\Sigma Q_d$ and $Q_d$ projects to a subspace of the orthogonal complement of the polynomials of degree up to $d$. Moreover using the Cauchy-Schwarz inequality for the inner-product $\\text{trace}(A,B^\\top)$ on matrices, the result follows for $H \\neq G$.

[@DFA_asymp] using our Lemma 1. No modifications are necessary for polynomial trending.

Then by the second lemma $(Z_1,Z_2,\\dots,Z_n,W_1,\\dots,W_n)$ is a stationary Gaussian vector in $j$. We may then use conditions on functions of a Gaussian Vector sufficient for a central limit theorem ([@CLT_GaussianVector], Theorem 2). It is possible to show that in the large n limit, the elements of the covariance matrix required by these conditions, which is proportional to $(I-P)\\Sigma_{1,j}(1-P)$, have order $1/j^2$, and thus the vector $(Z_1,\\dots,Z_n,W_1,\\dots,W_n)$ satisfies the conditions(since if the order is slower than this then the order of the DFA coefficients $\\text{cov}(F_{1,X_1,X_1}(n),F_{j,X_1,X_1}(n))$ is slower than $j^{-4}$ which is impossible by Proposition\u00a0\\[lem:cov\\_order\\]).

Secondly we show that for a given ratio of subsampling to window size the DCCA coefficients of both the unsubsampled version and the subsampled version tend to each other. Thirdly we show that these imply that in the limit of window size, the DCCA coefficients tend to the law of the coefficients of fractional Brownian motion. Together these imply that in a certain limit, the DCCA coefficients obey a central limit theorem with the same limiting distribution as the central limit proven above for fractional Brownian motion.\n\nPart I: We define the subsampled processes as $L_j(n)^{-1/2} X_j(nt)$. It is easy to show that the DCCA coefficients of the subsampled process tend to those of fBm; this follows by Proposition\u00a0\\[prop:Taqqu\\] for large window sizes.\n\nPart II: We have: $$F_{1,X_1,X_2}^2(n) = \\frac{1}{n^2}\\sum_{t=1}^n (X_1(t)- \\mathbb{P}_d(X_1(t))) (X_2(t)- \\mathbb{P}_d(X_2(t)))$$ Let $\\widehat{k}(X_j) = (X_j(k),X_j(2k),\\dots,X_j(t))$ and let $f^1_n$ be the least squares poly. fit of degree $d$ to $X_1$ and $f^1_{n/k}$ to $\\widehat{k}(X_j)$. Now we can use the Cauchy Schwarz inequality: $$\\begin{aligned}\n&& |F^2_{1,X_1,X_2}(n) - F^2_{1,\\widehat{k}(X_1),\\widehat{k}(X_2)}(n/k)|^2  \\\\\n&=& | <X_1-f^1_n,X_2-f^2_n> \\\\ \n&-& <\\widehat{k}(X_1)-f^1_{n/k},\\widehat{k}(X_2)-f^2_{n/k} >|^2 \\\\\n&=& | <X_1-f^1_n,X_2-f^2_n> - <\\widehat{k}(X_1)-f^1_{n/k},X_2-f^2_{n} > \\\\\n&+&  <\\widehat{k}(X_1)-f^1_{n/k},X_2-f^2_{n} > \\\\\n&-& <\\widehat{k}(X_1)-f^1_{n/k},\\widehat{k}(X_2)-f^2_{n/k} >|^2 \\\\\n& \\leq&  |<X_1-f^1_n-\\widehat{k}(X_1)+f^1_{n/k}, X_2-f^2_n>|^2\\\\\n &+& |<X_2-f^2_n-\\widehat{k}(X_2)+f^2_{n/k}, \\widehat{k}(X_1)-f^1_{n/k}>|^2  \\\\\n &\\leq&  |X_1-f^1_n-\\widehat{k}(X_1)+f^1_{n/k}| \\times | X_2-f^2_n| \\\\\n &+& |X_2-f^2_n-\\widehat{k}(X_2)+f^2_{n/k}| \\times | \\widehat{k}(X_1)-f^1_{n/k}| \\\\\n &\\leq& (|X_1-\\widehat{k}(X_1)| + |f^1_n-f^1_{n/k}|) \\times | X_2-f^2_n| \\\\\n  &+& (|X_2-\\widehat{k}(X_2)| + |f^2_n-f^2_{n/k}|) \\times | \\widehat{k}(X_1)-f^1_{n/k}|  \\label{eq:C_S}\n \\end{aligned}$$\n\nThe most problematic term which we need to bound here is the second term in each sum under the bracket.\n\nIt is possible to show, using Riemann sums, that, if $f^*$ is the poly. of degree $d$ which minimizes the generative mean squared error to $X$ ($f^* = \\text{min}_f \\int_0^1 (f(nt)-X(nt))^2 $) then:\n\n$$\\begin{aligned}\n|X - f_n|^2 &=& \\frac{1}{n}\\sum_{i=1}^n (X(i) - f_n)^2 \\\\\n&=& |X-f^*|^2 + \\mathcal{O}(\\text{max}((X-f^*)^2)/n^2)\\end{aligned}$$\n\nThus since least squares is a convex and differentiable optimization problem, we have that $f_n$ and $f^*$ are close to one another and so too are $f_n$ and $f_{n/k}$. I.e.:\n\n$$\\begin{aligned}\n|f_{n/k} - f_n|^2 &\\leq& |f_{n/k} - f^*|^2  +  |f_{n} - f^*|^2 \\\\\n&\\leq& r_{n}q_k\\end{aligned}$$\n\nTo obtain these rates $r_n$ and $q_k$ we need to obtain the parameter of strong convexity for the m.s.e.

Similarly for the polynomials of degree $d$ we have a non-degenerate and symmetric Hessian whose smallest eigenvalue is thus greater than zero.\n\nTherefore [@nesterov2004introductory]: $$\\begin{aligned}\n&& \\int_0^1 (X_1(nt)-f^1_n(nt))^2 dt - \\int_0^1(X_1(nt)-f^*(nt))^2 dt \\\\\n&\\geq& \\lambda_1 (a_n-a^*)^2 +  (b_n-b^*)^2\\end{aligned}$$\n\nHere we have the difference of two mean squared errors on the interval $[0,n]$. By assumption we have that with probability $1-\\frac{C n^H}{n}$: $$\\begin{aligned}\n\\frac{1}{n}\\sum_{i}^n ((a_n-a^*) i - (b_n-b^*))^2 \n&\\leq& \\frac{n-1}{2}((a_n-a^*)^2 +  (b_n-b^*)^2) \\\\\n&\\leq& D\\frac{n-1}{2}(\\text{max}((X-f^*)^2)/n^2) \\\\\n&\\leq&  D' n\\end{aligned}$$\n\nThus with probability $1-\\frac{C (n/k)^H}{n/k}$: $$\\begin{aligned}\n\\frac{1}{n/k}\\sum_{i}^{n/k} ((a_{n/k}-a^*) i - (b_{n/k}-b^*))^2 \n&\\leq&  D' {n/k}\\end{aligned}$$\n\nMoreover we have that $X_1$ and $X_2$ are almost surely H\u00f6lder continuous with exponent $H-\\phi$ for any $\\phi<0$ [@decreusefond1999stochastic] Thus there exists $E$ s.t.:\n\n$$\\begin{aligned}\n|X_1-\\widehat{k}(X_1)|^2 &=& \\frac{1}{n} \\sum (X_1(i) - X_i(mod(i,k)+k))^2 \\\\\n&\\leq& E k^{2H-2\\phi}\\end{aligned}$$ and with probability $1-\\frac{C n^H}{n}$: $$\\begin{aligned}\n|X_1-f^1_n| &\\leq& \\text{sup}|X_1| \\\\\n&\\leq& n\\end{aligned}$$ Thus we have, with probability at least $1-\\text{max}\\left(\\frac{Cn^H}{n} \\frac{C (n/k)^H}{C{n/k}},\\frac{C n^G}{n} \\frac{C(n/k)^G}{{n/k}}\\right)$ and a constant $A$: $$\\begin{aligned}\n  && \\frac{1}{n^{2H+2G}}|F^2_{j,X_1,X_2}(n) - F^2_{j,\\widehat{k}(X_1),\\widehat{k}(X_2)}(n/k)|^2 \\\\ \n  &\\leq& A \\frac{n (n/k) k^{H-\\phi} +n  (n/k) k^{G-\\phi}}{n^{2H+2G}} \\end{aligned}$$ in probability.\n\nThus let $0<\\delta < 1$ then, with probability at least $1-C' \\text{max}\\left( n^{(H-1)(1-\\delta)}, n^{G-1)(1-\\delta)}\\right)$, letting $k = n^\\delta$:\n\n$$\\begin{aligned}\n  && \\frac{1}{n^{2H+2G}}|F^2_{j,X_1,X_2}(n) - F^2_{j,\\widehat{k}(X_1),\\widehat{k}(X_2)}(n/k)|^2 \\\\ \n  &\\leq& A \\frac{ n^2 (n^\\delta)^{H-\\phi} + n^2 (n^\\delta)^{G-\\phi}}{n^{2H+2G+\\delta}} \\\\\n \\end{aligned}$$\n\nAnd this final expression tends to zero regardless of which values $H$ and $G$ take on. This implies that $F^2_{j,X_1,X_2}(n)$ tends in probability to the $k$-subsampled version as $n,k \\rightarrow \\infty$. Since $F^2_{j,X_1,X_2}$ is a stationary sequence, this convergence holds for all $j$. Thus we can use Boole\u2019s equality to show that $F^2_{X_1,X_2} \\rightarrow F^2_{\\widehat{k}(X_1),\\widehat{k}(X_2)}$ with constraints on $N$.\n\nI.e.: $$\\begin{aligned}\n    \\text{Pr}\\bigg( \\frac{1}{n^{2H+2G}}|F^2_{X_1,X_2}(n) - F^2_{\\widehat{k}(X_1),\\widehat{k}(X_2)}(n/k)|^2 \\\\ \n  \\leq BA \\frac{ n^2 (n^\\delta)^{H-\\phi} + n^2 (n^\\delta)^{G-\\phi}}{ n^{2H+2G+\\delta}} \\bigg)   \\label{eq:converge_multiple}\\\\\n  \\geq 1-[N/n]\\frac{2}{\\pi}\\text{max}\\left( n^{(H-1)(1-\\delta)}, n^{(G-1)(1-\\delta)}\\right)\n \\end{aligned}$$\n\nThus: provided $N = o(\\text{min}(n^{(1-H)(1-\\delta)+1},n^{(1-G)(1-\\delta)+1}))$ then the convergence in probability holds.\n\nPART III: to show convergence in distribution we use the portmanteau theorem [@klenke2008probability]. Let $s$ be a bounded continuous function and define $S(X_1,X_2) = \\frac{1}{n^{H+G}}F^2_{X_1,X_2}(n)$ and $S_{X_1^B,X_2^B}(n)  = \\frac{L(n)}{n^{H+G}}F^2_{X_1^B,X_2^B}(n)$ and $k = n^\\delta$. $$\\begin{gathered}\n   |\\mathbb{E}(s(S_{X_1,X_2}(n)) - \\mathbb{E}(s(S_{X_1^B,X_2^B}(n)))| \\\\\n   \\leq |\\mathbb{E}(s(S_{X_1,X_2}(n)) -  \\mathbb{E}(s(S_{\\widehat{k}(X_1),\\widehat{k}(X_2)}(n/k)))| \\\\ + | \\mathbb{E}(s(S_{\\widehat{k}(X_1),\\widehat{k}(X_2)}(n/k)))-\\mathbb{E}(s(S_{X_1^B,X_2^B}(n/k)))| \\\\\n   +  | \\mathbb{E}(s(S_{X_1^B,X_2^B}(n/k)))-\\mathbb{E}(s(S_{X_1^B,X_2^B}(n)))|\n \\end{gathered}$$\n\nThe first and the last lines converge in virtue of Part II (conv. in prob. implies conv. in dist.) and the second line converges in virtue of Part I.\n\n\\[prop:DFA\\_non\\_gauss\\] Under the assumptions of Proposition\u00a0\\[prop:non\\_gauss\\], as $n \\rightarrow \\infty$ and $[N/n] \\rightarrow \\infty$ then $\\frac{1}{n^{H+G}}F^2_{X_j,X_j}(n) \\xrightarrow{d} \\frac{L(n)}{n^{H+G}}F^2_{X_j^B,X_j^B}(n)$, where the $X_j^B$ is a fractional Brownian motion with the same Hurst parameter as $Y_i$.\n\nThe proof is identical to the proof made for the DCCA coefficients.\n\nUnder the assumptions of Proposition\u00a0\\[prop:non\\_gauss\\], as $n \\rightarrow \\infty$ and $[N/n] \\rightarrow \\infty$ then we have convergence to the central limit of Proposition\u00a0\\[prop:CLT\\] for the DCCA correlation coefficients assuming independence of $Y_1$ and $Y_2$. \\[prop:glue\\]\n\nEquation\u00a0 implies that we require:\n\n$$\\begin{gathered}\n \\sqrt{[N/n]}\\left(\\frac{ n^2 (n^\\delta)^{H-\\phi} + n^2 (n^\\delta)^{G-\\phi}}{ n^{2H+2G+\\delta}}\\right) \\rightarrow 0 \\\\\n\\text{i.e.  } \\sqrt{N}\\frac{ n^2 (n^\\delta)^{H-\\phi} + n^2 (n^\\delta)^{G-\\phi}}{ n^{2H+2G+\\delta+1/2}} \\rightarrow 0 \\\\\\end{gathered}$$\n\nThis statement is satisfiable while keeping $[N/n] \\rightarrow \\infty$. Thus we choose the rate on $N$ and $n$ to coincide with this rate and the rate given by Proposition\u00a0\\[prop:non\\_gauss\\].\n\nNote here that the rate we have calculated may be considerably improved by replacing the bound given by Boole\u2019s inequality with a more sophisticated bound calculated using distribution specific information w.r.t the structure of our time-series.\n\nWe finally note a mathematically interesting observation made by numerical evaluation of Equation\u00a0 of the Appendix.\n\nThe correlation between DCCA correlation coefficients is maximized asymptotically for low $H$ and the variance maximized for high $H$ under the null hypothesis.\n\n$\\begin{array}{c c c}\n\\includegraphics[width=50mm]{variance_against_H_G} & \\includegraphics[width=50mm]{maximum_corr_against_H_G_RATIO_200}  &  \\includegraphics[width=50mm]{maximum_corr_against_H_G_RATIO_110} \\end{array}$\n\nSoftware {#sec:software}\n========\n\nIn the accompanying software to this paper, we supply the following functions programmed in MATLAB[^9]:\n\n1.  [DCCA\\_fast.m]{} \u2013 a fast implementation of DCCA for arbitrary detrending degree $d$.\n\n2.  [DCCA\\_rho.m]{} \u2013 calculates the DCCA correlation coefficients $\\rho_{DCCA}$ on the basis of [DCCA\\_fast.m]{}.\n\n3.  [covariance\\_rho\\_DCCA.m]{} \u2013 exactly calculates $\\text{cov}(\\rho_{DCCA}(n),\\rho_{DCCA}(m))$ for small $N$.\n\n4.  [asymptotic\\_test.m]{} \u2013 implements the test given by Algorithm\u00a0\\[alg:test\\] using tabulation of the covariance plus the central limit theorem, using sampling to calculate the quantiles of the normal distribution. Tabulation of the covariance function for $d=1$ is saved in [.mat]{} files in the download package.\n\n[^1]: These include, for example, failure to converge to Gaussianity as the number of time-samples grows and minimax convergence rates in estimation\n\n[^2]: We use fractional Gaussian noise for illustration because it possesses certain properties of special significance which are possessed asymptotically by all time-series within the model of Equations\u00a0 and\u00a0; these properties are discussed later in the paper.\n\n[^3]: The software implementing the test in MATLAB is available at <http://www.user.tu-berlin.de/blythed/DCCA_matlab>\n\n[^4]: $L_i(t)/L_i(ct) \\rightarrow 1$ as $t \\rightarrow \\infty$ for any $c>0$.\n\n[^5]: Notice that this semi-parametric class includes the the class analysed by Bardet el al. [@DFA_asymp], viz. stationary Gaussian time-series with an auto covariance function proportional to $k^{2H-2}(1+\\mathcal{O}(1/k^\\beta))$ since $1+\\mathcal{O}(1/k^\\beta)$ is slowly varying at infinity.\n\n[^6]: We use [mvnrnd]{} in MATLAB.\n\n[^7]: This means that the $\\rho_{DCCA}$ coefficient also yields robustness to non-Gaussianity under the null hypothesis. Intuitively the reason for this is that although $F_{X_1,X_1}^2(n_1)$ has variance of the same order of magnitude as $F_{X_1,X_2}^2(n_1)$, the former has non-zero mean which implies it contributes no variance asymptotically.\n\n[^8]: Maple sheets are available for download at <http://www.user.tu-berlin.de/blythed/maple_DCCA>\n\n[^9]: The software is available for download from:
