WebJul 19, 2006 · Multivariate generalized linear mixed models Assume that for each of the m sets of items a univariate GLMM, as presented in Section 3.1 , can be specified. All the m univariate models can then be jointly modelled by specifying a joint distribution for the random effects. WebRepeated measures anova assumes that the within-subject covariance structure has compound symmetry. There is a single variance (σ 2) for all 3 of the time points and there is a single covariance (σ 1 ) for each of the pairs of trials. This is illustrated below. Stata calls this covariance structure exchangeable.
