Below are Rid]; values for all possible models predicting Y based upon 4 predictors (X1,...,X4 ). For each of the four variable selection methods, nd the nal model the method would choose. Use the Ridj values to make the decisions. The stopping criterion is that none of the new models under consideration have an Rid}- value larger than the current model.
