Web20 dec. 2024 · Generally, tests of homogeneity of variance are tests on the deviations (squared or absolute) of scores from the sample mean or median. If, for example, Group A’s deviations from the mean or median are larger than Group B’s deviations, then it can be said that Group A’s variance is larger than Group B’s. Webhomogeneity is eﬀective at overcoming many challenges in the con-text of ﬁnite normal mixtures. We ﬁnd that the limiting distribution of the EM-test is a simple function of the 0.5χ2 0 +0.5χ21 and χ2 1 dis-tributions when the mixing variances are equal but unknown and the χ2 2 when variances are unequal and unknown.
