NettetIn 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. They also inherit from GLMs the idea of extending linear mixed models to non-normal data.. GLMMs provide a broad range of models for the analysis … Nettet12. mar. 2024 · I am looking to get help into specifying the structure of the variance matrix within the gls() function in R's nlme package (or recommendations of other packages that can achieve the same thing).
