Generalized linear mixed models (glmms) have become extremely popular in recent years the main computational problem in parameter estimation for glmms is that, in contrast to linear mixed models, closed analytical expressions for the likelihood are not available. Models, generalized linear mixed imputation models and donor imputation methods (random, within class and nearest neighbour) are investigated and compared to existing methods which do not exploit this hierarchical struc.

Generalized linear mixed models when using linear mixed models (lmms) we assume that the response being modeled is on a continuous scale sometimes we can bend this assumption a bit if the response is an. 1) because i am a novice when it comes to reporting the results of a linear mixed models analysis, how do i report the fixed effect, including including the estimate, confidence interval, and p. The expectation-maximization algorithm has been advocated recently by a number of authors for fitting generalized linear mixed models however, the e-step typically involves analytically intractable integrals which have to be approximated.
