All of the Following Are Correct Formulae for the Homoskedasticity-Only

question 17

Short Answer

All of the following are correct formulae for the homoskedasticity-only F-statistic, with the exception of a. $\quad F = \frac { \left( S S R _ { \text {restricted } } - S S R _ { \text {unrestricted } } \right) / q } { S S R _ { \text {unrestricted } } / \left( n - k _ { \text {unrestricted } } - 1 \right) }$ .

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

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

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