The Homoskedasticity-Only F-Statistic Is Given by the Following Formula A \quad

The homoskedasticity-only F-statistic is given by the following formula a. $\quad F = \frac { \left( S S R _ { \text {restricted } } - S S R _ { \text {turrestricted } } \right) / q } { S S R _ { \text {unrestricted } } / \left( n - k _ { \text {unrestricted } } - 1 \right) }$ .

b. $F = \frac { \left( S S R _ { \text {restricted } } - S S R _ { \text {wnrestricted } } \right) / q } { S S R _ { \text {restricted } } / \left( n - k _ { \text {restricted } } - 1 \right) }$ .

c. $\quad F = \frac { \left( S S R _ { \text {umrestricted } } - S S R _ { \text {restricted } } \right) / q } { S S R _ { \text {unrestricted } } / \left( n - k _ { \text {umrestricted } } - 1 \right) }$ .

d. $\quad F = \frac { \left( S S R _ { \text {restricted } } - S S R _ { \text {unrestricted } } \right) / ( q - 1 ) } { S S R _ { \text {unrestricted } } / \left( n - k _ { \text {unrestricted } } \right) }$ .
