Access fitted models

[lorenzoFabbri]

In some cases I'd like to have access to the fitted models. For instance, to pass the model to other packages like marginaleffects. I see, for instance, that a glm is fitted here, but fit_object is a list of properties and I cannot seem to find the actual glm model. Am I missing something? Thanks!

thanks for the question, @lorenzoFabbri -- the short answer is that the fitted model object is unlikely to be preserved at the level that marginaleffects might require. you'll see just after the line that you point to that the S3 class that glm returns is stripped of much of its contents (https://github.com/tlverse/sl3/blob/devel/R/Lrnr_glm.R#L94-L104). this is done so as to minimize the memory footprint of the fitted model objects (of which there may be very many in a large stack)
