Question 1 :Stepwise regression can be a real timesaver in developing a model to describe the influence of several independent variables on a dependent. However, it does have some potential pitfalls. What, in your view, would be some of these pitfalls?

Question 2 : At the beginning of the course, we discussed 3 broad types of Business Analytics. These were 1) Descriptive Analytics, 2) Predictive Analytics, and 3) Prescriptive Analytics. Think of the example used in class of the wages data from the 1980s. When we built our model to fit the data, which of these 3 types of analytics was our primary focus? Why do you believe this?
