javanpst.tests.StatisticalTest

javanpst.tests.oneSample.signTest.SignTest

public class SignTest
extends StatisticalTest

The sign test This is a special case of the Population Quantile test where the quantile is 0.5 (the median) and the hypothesis value is 0. If a sequence is tested, the null hypothesis will be median=0 If a two-column table is analyzed, then the population of differences will be tested, thus testing which population is greater
