Questiоn 5: Ridge, Grоup Lаssо, аnd Elаstic Net Regularization - 19 points For this question, use trainData. a i. Perform ridge regression. Use 10-fold CV to find the optimal lambda value and display it. Fit a model with 100 values of lambda. ii. Display the coefficients at optimal lambda. How many variables were selected by ridge regression? Was this result expected? Explain. iii. Plot the coefficient path for ridge regression (6 points) b. i Perform group lasso regression. Use 10-fold CV to find the optimal lambda value and display it. Fit a model with 100 values of lambda (assign each predictor to its own group). ii. Extract coefficients at the optimal lambda. State the variables that are selected by group lasso regression. iii. Plot the coefficient path for group lasso regression. (6 points) c. State the advantage(s) of group lasso regression over traditional Lasso regression model. (2 points) d. i. Perform elastic net regression. Adjust the parameters so that the model places three times more emphasis on the lasso penalty compared to the ridge penalty. Use 10-fold CV to find the optimal lambda value and display it. Fit a model with 100 values of lambda. ii. Display the coefficients at optimal lambda. How many variables were selected by elastic net regression? (5 points)
