Method Detail

calcPEntropy

public double calcPEntropy(Vector<Double> data1D,
                           int m,
                           int d)

This method calculates the permutation entropy

Parameters:

data1D - 1D data vector

m - order of permutation entropy; m should not be greater than N/3 (N number of data points)!

d - delay

Returns:

PEntropy (sole double value)
