The permutation entropy
Did you know?
Permutation Entropy (PE) is a robust time series tool which provides a quantification measure of the complexity of a dynamic system by capturing the order relations between values of a time series and extracting a probability distribution of the ordinal patterns (see Henry and Judge, 2024). Visa mer The starting point of PE analysis is a one-dimensional time series. For illustration purposes, we will use the example given by Bandt and Pompe (2002). … Visa mer Our GAUSS code can be used to compute the permutation entropy of time series. Using the function pentropywe cancompute the permutation of our toy example. … Visa mer Bandt, C. and B.

Meanwhile, the better stability of RPE than that of PE in terms of data length has been validated in [ 31 ].
