Web5 mrt. 2010 · Test for Homogeneity of Variances. Levene's test ( Levene 1960 ) is used to test if k samples have equal variances. Equal variances across samples is called homogeneity of variance. Some statistical tests, for example the analysis of variance, assume that variances are equal across groups or samples. The Levene test can be … WebTherefore, the assumption of homogeneous variance-covariance matrices is violated. Notes One should be aware that, even though Hotelling's T-square test is robust to violations of assumptions of multivariate normality, the results of Bartlett's test are not robust to normality violations. carbs in bell peppers cooked
