SAS QUESTION: NOTE YOU MUST do the question using SAS code. The csv. file needed for the question CAN NOT be uploaded in the proper format. Please do NOT say it is incomplete. I am simply looking for the code steps to produce the answer, NOT the answer.

\fQ4 (12 points) Use the data from A4-Q4.csv to answer the following questions. (a) Use forward selection to select covariates for your model with significance level 5% to select a model. Clearly state the final model. Please show only relevant output for each step. (b) Use backwards selection to select covariates for your model with significance level 5% to select a model. Clearly state the final model. Please show only relevant output for each step. (c) Compare the models from (a) and (b). If they are different, briefly justify which model you may prefer. (d) Perform variable selection using AIC and BIC and compare the final models
