13. A large real estate company is trying to build a model to forecast total sales for the coming year for each of their agents and they have pulled data from their Finance records. They are trying to assemble the best data to build a Regression model.
a. Would it make sense to use the same data as we used above in the SAS model? Why or why not?
It would make sense to use the same data as we used above in the SAS model because in the given data, we already have several good predictors (or independent variables) for the total sales, which can be forecasted using the multiple regression model.
b. Recommend three data elements you think they probably have available to help them predict sales for each of their salespeople.
1. choosing the right statistical models
2. eliminating the predictors whose P-values are too high and hence are not statistically significant
3. identifying the correct null and alternative hypotheses before conducting a statistical test .
