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. WebJun 18, 2015 · The reason we do so is simple. The value of d2 when k=30 is close to the value of d2 derived from a continuous distribution of subgroups having the same subgroup size. This is why the table of d2 values is published up to k =15.
