I'm using scikit-learn's LogisticRegressionCV. Looks like the coefs_ field are the logistic regression coefficients. Is there any way to get p-values, z-values, or some measure of uncertainty for each feature? (For example, as discussed here in R.)
Unfortunately, scikit-learn does not have any such methods for the logistic regression (nor for the linear regression as a matter of fact). I found this which might be of interest for you, but honestly, I would try to stick to R for such tasks if you can.
