javanpst.tests.StatisticalTest

javanpst.tests.location.normalScoresTest.NormalScoresTest

public class NormalScoresTest
extends StatisticalTest

The Normal scores test. The Normal scores test (van der Warden test) uses inverse normal scores to asign ranks to data, before testing the null hypothesis of equal location. P-value is computed through a normal approximation. Ties are handled by the midranks method, and an appropriate reduction of variance is considered.
