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

Short Answer

The homoskedasticity-only F-statistic is given by the following formula a. $\quad F = \frac { \left( R _ { \text {unnestricted } } ^ { 2 } - R _ { \text {restricted } } ^ { 2 } / q \right. } { 1 - \left( R _ { \text {unrestricted } } ^ { 2 } \right) / \left( n - k _ { \text {unrestricted } } - 1 \right) }$ .

b. $\quad F = \frac { 1 - R _ { \text {unrestricted } } ^ { 2 } / q } { R _ { \text {unrestricted } } ^ { 2 } / \left( n - k _ { \text {unrestricted } } - 1 \right) }$ .

c. $\quad F = \frac { \left( R _ { \text {unrestricted } } ^ { 2 } - R _ { \text {unrestricted } } ^ { 2 } / q \right. } { 1 - \left( R _ { \text {unrestricted} } ^ { 2 } \right) / \left( n - k _ { \text {restricted } } - 1 \right) }$ .

d. $\quad F = \frac { \left( R _ { \text {restricted } } ^ { 2 } - R _ { \text {uurestricted } } ^ { 2 } / q \right. } { 1 - \left( R _ { \text {restricted } } ^ { 2 } \right) / \left( n - k _ { \text {restricted } } - 1 \right) }$ .
