Questiоn 3: Stepwise Regressiоn - 14 pоints For this question, use the trаinDаtа. Perform forward stepwise regression using BIC. Let the minimum model be the one with only an intercept, and the maximum model to be model1. Display the model summary of your final model. Call it forward_model. (2 points) Which variables were selected in the forward_model? Which regression coefficients are significant at the 99% confidence level in forward_model? (1 points) Perform backward stepwise regression using AIC. Let the minimum model be the one with only an intercept, and the maximum model to be model1. Display the model summary of your final model. Call it backward_model. (2 points) Which regression coefficients are significant at the 99% confidence level in backward_model? Are the selected variables different in forward and backward models? (2 points) Perform 2 Partial F-tests to compare the backward_model with the full model (model1) and the forward model with model1. What is your interpretation at the 95% confidence level? (2 points) Perform forward-backward stepwise regression model using AIC, starting with minimal model. Call it both_model.(2 points) Which variables are selected in both_model? Are all the selected variables significant at 99% level? Explain the reason. (2 points) What is the difference in variable selection between forward, backward and forward-backward stepwise regresssion? (1 points)
