WebAs Stijn pointed out, the k-s test returns a D statistic and a p-value corresponding to the D statistic. The D statistic is the absolute max distance (supremum) between the CDFs of the two samples. The closer this number is to 0 the more likely it is that the two samples were drawn from the same distribution. Webd = (M1 – M2) / spooled Where: M 1 = mean of group 1 M 2 = mean of group 2 s pooled = pooled standard deviations for the two groups.
