Class Wald_WolfowitzTest

java.lang.Object

javanpst.tests.StatisticalTest

javanpst.tests.twoSample.wald_WolfowitzTest.Wald_WolfowitzTest

public class Wald_WolfowitzTest
extends StatisticalTest

The Wald-Wolfowitz test. This tests maps the values of the ordered combined sample into a string sequence (e.g. XXYXYY, where X are the values of the first sample and Y are the values of the second sample). Then a Total Number of Runs test is carried out, where the alternative hypothesis (distinct distributions) is accepted when there are too few runs. The exact and the asymptotic p-values of the Total Number of Runs test is provided.
