Practical Predictive Analytics

Running the predict() function

Next, we will use the predict() function to score the test data in ChurnStudy.test, based upon the prediction model trained on ChurnStudy. The newdata= label designates the new dataset to be stored. The lp type is one of several types used for prediction, and this method uses the linear predictor:

pred_validation <- predict(CoxModel.1, newdata=ChurnStudy.test, type='lp')

The resulting predictions will be in log form.
