NettetUse GEE when you're interested in uncovering the population average effect of a covariate vs. the individual specific effect. These two things are only equivalent in linear models, but not in non-linear (e.g. logistic). To see this, take, for example the random effects logistic model of the j 'th observation of the i 'th subject, Y i j; Nettet20. The R package MuMIn also now has a function for calculating Nakagawa and Schielzeth's r-squared for mixed models. That is the function r.squaredGLMM () and you simply feed it a lmer object (from package lme4) to obtain the values. MuMIn has excellent documentation so you should be able to learn any details there.
