r-DFA : Robust Detrended Fluctuation Analysis

Robust Detrended Fluctuation Analysis

This MATLAB package is used to perform Robust Detrended Fluctuation Analysis (herein referred to as r-DFA). r-DFA is a procedure that feeds the results of the regular DFA to a series of statistical models in order to:
- determine a robust estimate of the global scaling exponent using Robust Regression,
- and to determine crossovers that produce statistically significant scaling exponents using Piecewise Linear Regression (a modification of Guido Albertin’s – 2013 PLR.m), ANCOVA and Multiple Comparison Procedure.
