In order to reduce the remaining predictors, use the`regsubsets()` function of the **leaps** package as follows: Run`regsubsets()` with exhaustive search on the training set.
Using adjusted R^2^s as a metric, choose the top three modelsfrom the exhaustive search.
Then use each of these models separately to predict thevalidation set. Compare RMSE and MAPE derived from the validationset.
Finally, describe the best model. need code in R studio and alsoDiscribe the model
