For GAM model, a internal function of GAM to check model assumption :
For some models,
plot(model) give answers to check model assumptions.
Packages exist for this purpose, such as performance package (https://github.com/easystats/performance). Unfortunately, this package doesn't work with tidymodels objects, even with the extract_fit_engine() function.
Are there equivalent functions included in tidymodels for testing model assumptions ?
Thank you for your help,
