Results are rounded to the closest integers and ordered by their average value (the last couple (row) is the best performing on average across subjects). Columns refer to subjects (S1–S12) and rows to each feature couple (Ave, Average; Pea, Peak; Var, Variance; Skew, Skewness; Kurt, Kurtosis; AUC, Area Under the Curve; Cov, Covariance; Pear, Pearson's; Spear, Spearman's; Coh, Coherence; WTC, Wavelet Coherence).
