Conditions under Which Mean Square Ratios in Repeated Measurements Designs Have Exact F-Distributions
重复测量设计中均方比服从精确 F 分布的条件
Investigation is made of the character of the covariance matrix which will result in exact F-distributions for the treatments and interaction variance ratios in repeated measurements designs. It is shown, assuming multivariate normality, that the matrix may exhibit a more general character than is typically implied to be essential. Equality of variances and equality of covariances, with identical matrices for all levels of a second treatment factor, are sufficient but not…
