(Round to one decimal place as needed.)
e. Which of these three models do you think is the best predictor of price-to-book-value ratio?

Steps to do Regression in Excel
a)
Model 1

Price/Book Value Ratio = 2.3388 + 0.0702 * Return on Equity
b)
Model 2

Price/Book Value Ratio = 3.1444 + 0.0306 * Growth
c)
Model 3

Price/Book Value Ratio = 1.9539 + 0.0602 * Return on Equity + 0.0216 * Growth
d)
Start with the part (a) model.
The adjusted r2 shows that 33.03% of the variation in Price/Book Value Ratio is explained by Return on Equity correcting for the number of independent variables in the model.
(Round to one decimal place as needed.)
Compute and interpret the adjusted r2 for the part (b) model.
The adjusted r2 shows that 18.69% of the variation in Price/Book Value Ratio is explained by Growth correcting for the number of independent variables in the model.
(Round to one decimal place as needed.)
Compute and interpret the adjusted r2 for the part (c) model.
The adjusted r2 shows that 41.47% of the variation in Price/Book Value Ratio is explained by Return on Equity and Growth correcting for the number of independent variables in the model.
e)
Even though R Square for Model 3 is highest, still Model 1 is the best Model as Model 3 is being penalized for including an irrelevant independent variable. (Shown by the gap between R Square and Adjusted R Square)
