Class KolmogorovTwoSampleDistribution

java.lang.Object

javanpst.distributions.tests.KolmogorovTwoSampleDistribution

public class KolmogorovTwoSampleDistribution
extends java.lang.Object

An implementation of the Kolmogorov distribution for two samples. Uses a Singleton pattern to ensure only an instance of the class is allowed.

Method Summary

Modifier and Type	Method and Description
