Detrended Fluctuation Analysis (DFA) The procedure for Detrended Fluctuation Analysis is similar to SDA, except that within each bin, the signal is first detrended, what remains is then considered the residual variance. The logic is the same, the way the average residual variance scales with the bin size should be an indication of the ...
