WebJan 9, 2015 · Finally, it might be better (and simpler) to use predictive model with "built-in" feature selection, such as ridge regression, the lasso, or the elastic net. Specifically, try the method=glmnet argument for caret, and compare the cross-validated accuracy of that model to the method=lmStepAIC argument. My guess is that the former will give you ... WebFeature selection is usually used as a pre-processing step before doing the actual learning. The recommended way to do this in scikit-learn is to use a Pipeline: clf = Pipeline( [ ('feature_selection', SelectFromModel(LinearSVC(penalty="l1"))), ('classification', RandomForestClassifier()) ]) clf.fit(X, y) WebAs a result of Minitab's second step, the predictor x 1 is entered into the stepwise model already containing the predictor x 4. Minitab tells us that the estimated intercept b 0 = 103.10, the estimated slope b 4 = − 0.614, and the estimated slope b 1 = 1.44. The P -value for testing β 4 = 0 is < 0.001. lehigh valley hospital - dickson city
