A note on the biasedness and unbiasedness of two-sample Kolmogorov–Smirnov test
Abstract This paper deals with the two-sample Kolmogorov–Smirnov test and its biasedness. This test is not unbiased in general in case of unequal sample sizes. We identify most biased distributions for some values of significance level α . Moreover, we discovered that there exists numbers of observations and significance levels α such that this test is unbiased at level α .
