WebFeb 5, 2024 · R ships with the mgcv package, which fits GAMs using penalized regression splines as I outline above. You control the size (dimensionality) of the basis for each smooth using the argument k. There is no argument df. Like I said, GAMs are a broad church and there are many ways to fit them. WebIn mgcv, by default the estimated parameters are chosen via a generalized cross validation, or GCV, approach, and that statistic is reported in the summary. It modifies the loss …

Webmgcv.package: Mixed GAM Computation Vehicle with GCV/AIC/REML smoothness estimation and GAMMs by REML/PQL Description mgcv provides functions for generalized additive modelling ( gam and bam) and generalized additive mixed modelling ( gamm, and random.effects ). WebI should update this answer a little given some new functionality in the mgcv package in terms of splines for marginal bases. That said, I don't agree that you need to fix the degrees of freedom for the spline. The key is to ensure that the bases for the models are appropriately nested.
