针对有序备择的多总体方差齐性检验AI 解读

Several statistics are investigated for testing the homogeneity of a set of variances of normal populations against ordered alternatives. The null distributions of these statistics are studied. Comparisons of powers of the tests are also made by Monte Carlo experiments. The test based on the modified Bartlett's statistic M* is found to perform best.

针对有序备择的一组方差齐性检验AI 解读

SuIMMAPRY Several statistics are investigated for testing the homogeneity of a set of variances of normal populations against ordered alternatives. The null distributions of these statistics are studied. Comparisons of powers of the tests are also made by Monte Carlo experiments. The test based on the modified Bartlett's statistic M* is found to perform best. For testing the homogeneity of variances of several normal distributions test statistics such as M by Bartlett…
