Glmm homoscedasticity
WebAn alternative to GEE is the class of generalized linear mixed models (GLMM). These are fully parametric and model the within-subject covariance structure more explicitly. GLMM is a further extension of GLMs that permits random effects as well as fixed effects in the linear predictor. Fix Effect vs Random Effect WebHomoscedasticity, or homogeneity of variances, is an assumption of equal or similar …

WebGeneralized linear mixed models extend the linear model so that: The target is linearly … WebGeneralized linear mixed model. In statistics, a generalized linear mixed model (GLMM) is an extension to the generalized linear model (GLM) in which the linear predictor contains random effects in addition to the usual fixed effects. [1] [2] [3] They also inherit from GLMs the idea of extending linear mixed models to non- normal data.
