Which Stepwise regression method carries out the following starting steps? 1. Establish the minimum model and the predictors that must be included. 2. Fit full model with p explanatory predictors, and compute AIC for this model. 3. Next, fit p regression models by removing one explanatory predictor each time and compute AIC for each of them. 4. Select the predictor whose removal yields the smallest AIC value and remove it from the full model.
