Notes. We consider a confidence level of 98% in order to reject the null hypothesis H0 (both samples coming from the same underlying continuous distribution). D is the maximum deviation between the empirical distribution functions of samples 1 and 2; p corresponds to the estimated likelihood of the null hypothesis, a value that is known to be reasonably accurate for sample sizes for which neff= (n1 × n2)/(n1 + n2) ≥ 4; (0): accept null hypothesis; (1): reject null hypothesis.
