Q. 4 (30 points) We are using the same MBTI dataset. We fit a model using the four scales as predictors of whether a subject drinks alcohol frequently. Answer the following questions. (a) (10 pts) Conduct a model goodness-of-fit test, and interpret. If you were to sim- plify the model by removing a predictor, which would you remove? Why? (b) (10 pts) Report AIC values for the model with the four main effects and the six interaction terms; the model with only the four main effect; the model with no predictors. According to this criterion, which model is preferred? Explain the rationale for using AIC. (c) (10 pts) Using the MBTI data set, use model-builing mehtods to select a model for this alcohol response variable. Q. 4 (30 points) We are using the same MBTI dataset.
