Linear regression predict_proba
NettetWhen method is one of {‘predict_proba’, ‘predict_log_proba’, ‘decision_function’} (unless special case above): (n_samples, n_classes) If estimator is multioutput, an extra dimension ‘n_outputs’ is added to the end of each shape above. See also cross_val_score Calculate score for each CV split. cross_validate
