(1 reply) Hi, all of the internet discussions on statsmodels vs sklearn are from 2013 or before. While the X variable comes first in SKLearn, y comes first in statsmodels.An easy way to check your dependent variable (your y variable), is right in the model.summary (). First, we define the set of dependent(y) and independent(X) variables. Alternatively, the estimator LassoLarsIC proposes to use the Akaike information criterion (AIC) and the Bayes Information criterion (BIC). discrete.
