Question:
In Figure 11.35, we discovered a potential multicollinearity problem. It appeared that home size was no longer a significant input given the presence of land area.
(a) Run a single regression based on just land area. What are the coefficients?
(b) What is the R2 value for this model? How does it compare with the adjusted R2 value for the multiple regression model shown in Figure 11.35? Which model appears to be a better predictor of the future of housing prices for this data set?
