Witryna9 lip 2015 · 1 Answer. You insisted with your syntax that all the variables be kept together, so Stata has nowhere to go from where it started in this case. Hence there can be nothing stepwise with your syntax: it's either all in or all out. See the help: a varlist in parentheses indicates that this group of variables is to be included or excluded together. WitrynaOverall, stepwise regression is better than best subsets regression using the lowest Mallows’ Cp by less than 3%. Best subsets regression using the highest adjusted R-squared approach is the clear loser …

Scikit-learn indeed does not support stepwise regression. That's because what is commonly known as 'stepwise regression' is an algorithm based on p-values of coefficients of linear regression, and scikit-learn deliberately avoids inferential approach to model learning (significance testing etc).
