Personally, I'd use mgcv::gam and let it choose the dfs (you can simply add the non-splines in the same way as in glm ). That way you get its guess of the degree of non-linearity. When the edf (estimated d.f.) are around 1, cont_var has a near-linear effect and the glm is fine. Feb 15, 2024 at 21:35. very interesting question.
