gammi:Generalized Additive Mixed Model Interface
An interface for fitting generalized additive models (GAMs) and generalized additive mixed models (GAMMs) using the
'lme4' package as the computational engine, as described in
Helwig (2024) <doi:10.3390/stats7010003>. Supports default and
formula methods for model specification, additive and tensor
product splines for capturing nonlinear effects, and automatic
determination of spline type based on the class of each
predictor. Includes an S3 plot method for visualizing the
(nonlinear) model terms, an S3 predict method for forming
predictions from a fit model, and an S3 summary method for
conducting significance testing using the Bayesian
interpretation of a smoothing spline.
