Question:
In American college football, Rivals.com constructs a widely followed index for rating colleges based on the high school players they recruit and Jeff Sagarin constructs a highly regarded system for rating college football teams based on their performance. Table 10.5 shows the 2008 performance ratings and the 2004–2008 recruiting ratings for the 20 colleges with the highest recruiting averages over this 5-year period. (Five years of recruiting data are used because players often “red shirt”
their first year by practicing with the team but not playing, thereby maintaining their 4 years of college eligibility.) Use these data to estimate a multiple regression model with performance the dependent variable and the five recruiting scores the explanatory variables.
a. Do all of the recruiting coefficients have plausible signs?
b. Which, if any, of the recruiting coefficients are statistically significant at the 5 percent level?
c. Which team overperformed the most, in that its performance was much higher than predicted by your estimated equation?
d. Which team underperformed the most, in that its performance was much lower than predicted by your estimated equation?
