Model Selection & Functional Form: Female (takes a value for 1 if female, 0 if not female) and Non-White (and value of 1 if NonWhite, 0 if white) are dummy variables. Age is measured continuously in years, and Age Squared is the square of Age. Education is measured in years, Earnings measured in dollars, and Log Earnings are the log transformation of earnings. Are the predictor variables in Models A & B statistically significant at the 5% significance level? Carefully interpret and explain the coefficients for Female, Non-White, Age Squared and Education in models A and B. Compare Model A to Model B. Which model would use for purposes of prediction and why? In your preferred model, should we add Age Squared? Is your chosen model a good model? Explain why or why not.
