Notes. For each comparison (Singles-Pairs, Singles-Groups, Pairs-Groups), we report the p-values obtained from the Kolmogorov-Smirnov (KS), Anderson-Darling (AD), and Cramér-von Mises (CVM) tests, listed in that order. We used the twosamples package (Dowd 2020) and Cramer package, available in the R statistical environment. The value of the Anderson-Darling statistic (A2) is also provided, computed using the Ksamples package available also in R environment.
