The test statistic for this Chow test is
A) $ \frac{USSpooled / k+1}{\left(U S S_{4}+U S S_{2}\right) / n-2(k+1)} $

B) $\frac { \text { USS } _ { 1 } + \text { USS } _ { 2 } / k + 1 } { \text { (USS } \left. _ { 1 } + \text { USS } _ { 2 } \right) / n - 2 ( k + 1 ) }$

C) $\frac { \left( \text { USS } _ { p o o l e d } - \left( \text { USS } _ { 1 } + \text { USS } _ { 2 } \right) \right) / k + 1 } { \left( U S S _ { 1 } + \text { USS } _ { 2 } \right) / ( k + 1 ) }$

D) $\frac { \left( \text { USS } _ { p o o l e d } - \left( \text { USS } _ { 1 } + U S S _ { 2 } \right) \right) / k + 1 } { \left( U S S _ { 1 } + U S S _ { 2 } \right) / n - 2 ( k + 1 ) }$

Quizplus · Accepted Answer

The correct formula for the test statistic in a Chow test is given by (USSpooled - USS1 - USS2)/[(USS1+USS2)/(n-2*(k+1))], which matches option D.

The Test Statistic for This Chow Test Is A) USSpooled/k+1(USS4+USS2)/n−2(k+1) \frac{USSpooled / k+1}{\left(U S S_{4}+U S S_{2}\right) / n-2(k+1)} (USS4​+USS2​)/n−2(k+1)USSpooled/k+1​

The Test Statistic for This Chow Test Is
A) $\frac{USSpooled / k+1}{\left(U S S_{4}+U S S_{2}\right) / n-2(k+1)}$
