question 31

Multiple Choice

All of the following are correct formulae for the homoskedasticity-only F-statistic, with the exception of

• A) \(F = \frac { \left( S S R _ { \text {restricted } } - S S R _ { \text {unrestricted } } \right) / q } { S S R _ { \text {unrestricted} } / \left( n - k _ { \text {unrestricted } } - 1 \right) }\)
• B) \(F = \frac { \left( S S R _ { \text {unrestricted } } - S S R _ { \text {restictad } } \right) / q } { S S R _ { \text {restricted} } / \left( n - k _ { \text {restricted } } - 1 \right) }\)
• D) \(F = \left( \frac { S S R _ { \text {restricted } } } { S S R _ { \text {unrestricted } } } - 1 \right) \times \frac { \left( n - k _ { \text {unrestricted} } - 1 \right) } { q }\)
