If the angle between two lines of regression is \theta, then the value of \theta will be

Correct Answer is : tan−1[bxy−1byx1+bxybyx]

\tan ^{-1} [ {b_{y x}-{1}/{b_{x y}}}/{1+ {b_{x y}}/{b_{y x}}}]

\tan ^{-1} [ {b_{y x}-b_{x y}-1}/{b_{x y}+b_{y x}}]

\tan ^{-1} [ {b_{x y}-{1}/{b_{y x}}}/{1+ {b_{x y}}/{b_{y x}}}]

\tan ^{-1} [ {b_{y x}-b_{x y}}/{1+b_{y x} \cdot b_{x y}}]
