question 23

Essay

Using the California School data set from your textbook, you decide to run a regression of the average reading score (ScrRead)on the average mathematics score (ScrMaths). The result is as follows, where the numbers in parenthesis are homoskedasticity only standard errors: $\widehat{\text { ScrRead }}$ = 8.47 + 0.9895×ScrMaths
(13.20)(0.0202)
N = 420, R² = 0.85, SER = 7.8
You believe that the average mathematics score is an unbiased predictor of the average reading score. Consider the above regression to be the unrestricted from which you would calculate SSR_Unrestricted . How would you find the SSR_Restricted? How many restrictions would have to impose?
