Recurrence quantification analysis (RQA), diagonal line structures; percentage determinism (%DET), mean diagonal line length (Lmean), vertical line structure; percentage laminarity (%LAM), mean vertical line length (trapping time, TT). Detrended fluctuation analysis (DFA), short term DFA (DFA1), longer term DFA (DFA2) and the time scale that separates DFA1 and DFA2; DFAtau.
