Prove that
$F = \frac { \left( S S R _ { \text {restricted } } - S S R _ { \text {unrestriced } } \right) / q } { S S R _ { \text {urrestricted } } / \left( n - k _ { \text {unrestriced } } - 1 \right) } = \frac { \left( R _ { \text {unrestricted } } ^ { 2 } - R _ { \text {restricted } } ^ { 2 } / q \right. } { 1 - R _ { \text {unrestrocted } } ^ { 2 } / \left( n - k _ { \text {unrestriceed } } - 1 \right) }$
