Table 2 Maximum median values of NCSE with the maximum significance level from threshold ranges from 1 to 30 and MSE for scale 1 to 20 using non-parametric Wilcoxon rank sum test

From: Symbolic time series analysis of electroencephalographic (EEG) epileptic seizure and brain dynamics with eye-open and eye-closed subjects during resting states
