WebMay 5, 2024 · Abstract. In this chapter we introduce the Generalized Additive Model (GAM). GAMs enable the analyst to investigate non-linear functional relations between a response variable and one or more predictors. Furthermore, GAMs provide a principled framework for studying interactions involving two or more numeric predictors. WebJust like in random effects in a mixed model. The smoothness parameter for random effects smooths is proportional to the variance parameter (IIRC it is actually related to the inverse of the variance parameter, the precision, rather than the variance itself). ...

Fits the specified generalized additive mixed model (GAMM) to data, by a call to lme in the normal errors identity link case, or by a call to glmmPQL from the MASS library otherwise. In the latter case estimates are only approximately MLEs. fouche blignaut
