Change Reference/Baseline in GLM
I am sure there is a super easy way to do this but I can't find it. How can I change the reference level for a categorical variables for my glm?
In python it would be something like this: https://stackoverflow.com/questions/22431503/specifying-which-category-to-treat-as-the-base-with-statsmodels

Found the solution thanks. Its a matter of defining comparison groups in nominal to numerical operator.

Correct. Although you actually don't need the comparison group method at all, the GLM implementation can handle the dummy coding approach, which is a bit more popular. So either works fine.
