Hi, what is the Python equivalent for R step() function of stepwise regression with AIC as criteria?
Is there an existing function in statsmodels.api?
Forget stepwise, it is unstable. For a better solution see the attached. Best, D. Booth
I developed this repository link. My Stepwise Selection Classes (best subset, forward stepwise, backward stepwise) are compatible to sklearn. You can do Pipeline and GridSearchCV with my Classes.
