Homework 8 due 3/6/19 @ 8pm PT Question 11.1 I load the uscrime.txt file into R. 1) Stepwise Regression First I create a linear regression model using all the factors.

Removing So would lower the AIC to 512.65 so it removed it. Then by removing Time, the AIC would lower to 511.01. At 511.01, if it removed LF the AIC would drop yet again; so it removed it. This cycle kept going until the removal of any additional factors would not result in a lower AIC. The lowest stepwise regression could get the AIC to be was 503.93. I then call the summary function on the stepwise model to get more information. My model is therefore y = -6,426.1 + 93.3M + 180.1Ed + 102.7Po1 + 22.3MF -6,086.6U1 + 187.4U2 + 61.3Ineq – 3,796Prob. I compute the R2, AIC, and BIC of the model. [Show More]
