A distance-based test of independence between two multivariate time series

B Chu - Journal of Multivariate Analysis, 2023 - Elsevier
We contribute to recent research on distance correlation by extending its capability to test for
independence between two time series. The proposed test is a Portmanteau-type test based …

Debiased learning and forecasting of first derivative

WW Wang, J Lu, T Tong, Z Liu - Knowledge-Based Systems, 2022 - Elsevier
In the era of big data, there are many data sets recorded in equal intervals of time. To model
the change rate of such data, one often constructs a nonparametric regression model and …

Goodness-of-fit testing for time series models via distance covariance

P Wan, RA Davis - Journal of Econometrics, 2022 - Elsevier
In many statistical modeling frameworks, goodness-of-fit tests are typically administered to
the estimated residuals. In the time series setting, whiteness of the residuals is assessed …

Detecting practically significant dependencies in infinite dimensional data via distance correlations

H Dette, M Kroll - arXiv preprint arXiv:2411.16177, 2024 - arxiv.org
In this paper we take a different look on the problem of testing the independence of two
infinite dimensional random variables using the distance correlation. Instead of testing if the …

Multivariate differential association analysis

H Song, MC Wu - Stat, 2024 - Wiley Online Library
Identifying how dependence relationships vary across different conditions plays a significant
role in many scientific investigations. For example, it is important for the comparison of …

Exploring the Impact of the Signal-to-Noise Ratio Assumption on the Time Series Bootstrap Pairwise Dependence Hypothesis Test

T Koutsellis, A Nikas, S Choumas… - … & Applications (IISA), 2023 - ieeexplore.ieee.org
Distance correlation (dCorr) is a test statistic that can identify non-linear dependence
patterns between random variables. Variations of dCorr have been applied in sequences of …

Test for independence of long-range dependent time series using distance covariance

A Betken, H Dehling - arXiv preprint arXiv:2107.03041, 2021 - arxiv.org
We apply the concept of distance covariance for testing independence of two long-range
dependent time series. As test statistic we propose a linear combination of empirical …
