"The Brunner Munzel test (also called the Generalized Wilcoxon Test) is a non parametric statistical test for stochastic equality of two samples. Stochastic equality is a similarity measure between two populations , which means that the populations have roughly the same frequency of greater values. See more This heteroskedasticity–robust test can be used as an alternative to the Wilcoxon-Mann-Whitney (WMW) rank sum test (Fagerland, 2012). … See more The null hypothesis for the test is H0 = 0.5, which implies stochastic equality. The alternate hypothesis is H0≠ 0.5, which means that greater values occur in one of the groups. If the null hypothesis is rejected, it should be … See more Brunner, E., and Munzel, U.
