  "Description": "An interface for fitting generalized additive models\n(GAMs) and generalized additive mixed models (GAMMs) using the\n'lme4' package as the computational engine, as described in\nHelwig (2024) <doi:10.3390/stats7010003>. Supports default and\nformula methods for model specification, additive and tensor\nproduct splines for capturing nonlinear effects, and automatic\ndetermination of spline type based on the class of each\npredictor. Includes an S3 plot method for visualizing the\n(nonlinear) model terms, an S3 predict method for forming\npredictions from a fit model, and an S3 summary method for\nconducting significance testing using the Bayesian\ninterpretation of a smoothing spline.",
