java.lang.Object

javanpst.tests.StatisticalTest

javanpst.tests.twoSample.K_STest.K_STest

public class K_STest
extends StatisticalTest

The Kolmogorov-Smirnov test for two samples This test can be applied to test the null hypothesis of equal distributions against the one side and two-side alternatives. The exact p-value is computed is the number of values per sample is equal or less than 40. In addition, an approximation to the normal distribution is computed.
