"WebJan 20, 2024 · Package gamm4 is an alternative, which allows AIC type model selection for generalized models. When using gamm or gamm4, the reported AIC is different for the gam object and the lme or lmer object. Why is this? There are several reasons for this. The most important is that the models being used are actually different in the two representations. " - Bayesian package lme r
