11.4 Test for Homogeneity - Statistics OpenStax
WebHomogeneity of variance-covariance matrices assumption: Box’s M test: This test is used to test the multivariate homogeneity of variance-covariance matrices assumption. An insignificant value of Box’s M test shows that those groups do not differ from each other and would meet the assumption. WebThis article describes statistical tests for comparing the variances of two or more samples. Equal variances across samples is called homogeneity of variances. Some statistical tests, such as two independent samples T-test and ANOVA test, assume that variances are equal across groups. The Bartlett’s test, Levene’s test or Fligner-Killeen ... WebDistance-based tests of homogeneity of multivariate dispersions, which can be based on any dissimilarity measure of choice, are proposed here. They rely on the rotational invariance of either the multivariate centroid or the spatial median to obtain measures of spread using principal coordinate axes. The tests are manaramarine.com
