Abstract:

Problem of making inferences on a widely used repeated measures model is considered without the assumption of equal error variances. By taking the generalized approach we derive the formulae for computing exact generalized p-values for testing the equality of treatment effects, occasion effects, and their interactions. We also provide the formulae for making inferences about the variance components of the model. Superiority of the generalized p values over the classical F-test is demonstrated by means of an example.
