Additional file 3. Permutation entropy test. Normalized permutation entropy for 48 hr of data using different values of n, τand window lengths ts in minutes. All figures were also normalized by their respective maximum value. In n = 7 plots, 1-minute window (red) is not considered since the minimum number of data samples to compute h is n!.
