We examine the scaling regime for the detrended fluctuation analysis (DFA) -the most popular method used to detect the presence of long memory in data and
the fractal structure of time series. First,...
Multifractal detrended cross-correlation analysis for two nonstationary signals
Multifractal detrended cross-correlation analysis nonstationary signals

It is ubiquitous in natural and social sciences that two variables, recorded temporally or spatially in a complex system, are cross-correlated and possess multifractal features. We propose a new meth...
