We prefer the model containing the three predictors X3‚ X1 and X4‚ because its R2-value is 0.9615‚ which is higher than 0.9330 (the model containing just two predictors X3 and X1) and 0.8047(the model containing just one predictor X3). Checking the mean square error of the three models we find that the model we selected as best model has the smallest mean square error 16.581‚ which is good.
