Repeated Measures

Model Specification for Repeated Measures Models

Learn how to specify a repeated measures model in fitrm.

Mauchly's Test of Sphericity

Learn the test of sphericity used in repeated measures models.

Compound Symmetry Assumption and Epsilon Corrections

Learn the different epsilon corrections used in p-value calculations in the repeated measures ANOVA when the compound symmetry assumption fails.

Multivariate Analysis of Variance for Repeated Measures

Learn the four different methods used in multivariate analysis of variance for repeated measures models.

Wilkinson Notation

Wilkinson notation provides a way to describe regression and repeated measures models without specifying coefficient values.



MANOVA is a form of ANOVA with multiple response variables. It determines whether the entire set of means is different from one group to the next.
