> Kolmogorov-Smirnov test (see [1]) is used to test if one sample against a known probability
density functions or if two samples are from the same distribution. To evaluate the test statistic,
the Kolmogorov-Smirnov distribution is used. Quite good asymptotics exist for the one-sided
test, but it's more difficult for the two-sided test.
