Essay

To calculate the homoskedasticity-only overall regression $F$ -statistic, you need to compare the $S S R _ { \text {restricted } }$ with the $S S R _ { \text {urrestricted } }$ . Consider the following output from a regression package, which reproduces the regression results of testscores on the studentteacher ratio, the percent of English learners, and the expenditures per student from your textbook:

Dependent Variable: TESTSCR
Method: Least Squares
Date: 07/30/06 Time: 17:55
Sample: 1420
Included observations: 420


Sum of squared resid corresponds to $S S R _ { \text {unrestricted } }$ . How are you going to find $S S R _ { \text {restricted } }$ ? ii
