Ridgeclassifier predict_proba

WebAccording to the documentation, a Ridge.Classifier has no predict_proba attribute. This must be because the object automatically picks a threshold during the fit process. Given the documentation, I believe there is no way to plot a ROC curve for this model. Fortunately, you can use sklearn.linear_model.LogisticRegression and set penalty='l2'.
