dev.nm.stat.test.distribution.kolmogorov.KolmogorovSmirnov1Sample

public class KolmogorovSmirnov1Sample
extends KolmogorovSmirnov

The one-sample Kolmogorov-Smirnov test (one-sample KS test) compares a sample with a reference probability distribution. This class computes the one-sample Kolmogorov-Smirnov statistic.
