In this work we develop the asymptotic theory of the Detrended Fluctuation Analysis (DFA) and Detrended Cross-Correlation Analysis (DCCA) for trend-stationary stochastic processes without any assumption on the specific form of the underlying distribution. All results are derived without the assumption of non-overlapping boxes for the polynomial fits. We prove the stationarity of the DFA and DCCA, viewed as a stochastic processes, obtain closed forms for moments up to second order, including the… Expand

Genomic Surveillance of COVID-19 Variants with Language Models and Machine Learning
Dimensions of Concern (DoCs) are derived in the latent space of SARS-CoV-2 mutations and demonstrate their potential to provide a lead time for predicting the increase of new cases and are extensible to related challenges such as immune escape, pathogenicity modeling, and antimicrobial resistance.

Asymptotic Properties of the Detrended Fluctuation Analysis of Long-Range-Dependent Processes
Asymptotic properties of the DFA of the fractional Gaussian noise of the FGN are provided and the convergence of the semiparametric estimator of the Hurst parameter is established. Expand
Statistical tests for power-law cross-correlated processes.
Using ρ(DCCA)(T,n), it is shown that the Chinese financial market's tendency to follow the U.S. market is extremely weak and an additional statistical test is proposed that can be used to quantify the existence of cross-correlations between two power-law correlated time series. Expand
Detecting long-range correlations with detrended fluctuation analysis
We examine the detrended fluctuation analysis (DFA), which is a well-established method for the detection of long-range correlations in time series. We show that deviations from scaling which appearExpand
A rigorous and efficient asymptotic test for power-law cross-correlation
Podobnik and Stanley recently proposed a novel framework, Detrended Cross-Correlation Analysis, for the analysis of power-law cross-correlation between two time-series, a phenomenon which occursExpand
Robust Statistical Detection of Power-Law Cross-Correlation
A theory and method is proposed which allows for the first time the presence of power-law cross-correlations between amplitudes of the alpha and beta frequency ranges of the human electroencephalogram, thus establishing meaningful relationships between processes in complex physical systems. Expand
Detrended cross-correlation analysis: a new method for analyzing two nonstationary time series.
A new method is proposed, detrended cross-correlation analysis, which is a generalization of detrende fluctuation analysis and is based on detrending covariance, designed to investigate power-law cross correlations between different simultaneously recorded time series in the presence of nonstationarity.

We present a set of stylized empirical facts emerging from the statistical analysis of price variations in various types of financial markets. We first discuss some general issues common to allExpand
On convergence properties of sums of dependent random variables under second moment and covariance restrictions
Abstract For a sequence of dependent square-integrable random variables and a sequence of positive constants { b n , n ≥ 1 } , conditions are provided under which the series ∑ i = 1 n ( X i − E X i )Expand
DCCA cross-correlation coefficient: Quantifying level of cross-correlation
Abstract In this paper, a new coefficient is proposed with the objective of quantifying the level of cross-correlation between nonstationary time series. This cross-correlation coefficient is definedExpand
