Question: Show that Eq. (7.4.7) can also be expressed as where b 23 is the slope coefficient in the regression of X 2 on X 3

Show that Eq. (7.4.7) can also be expressed as

Ey,(x2 – b23x3i) E(x2; – b23x3)2 net (of x3) covariation between y and x2 net (of 3) variation in x2


where b23 is the slope coefficient in the regression of X2 on X3. Recall that b23 = Σx2ix3i / Σx23i.

Ey,(x2 b23x3i) E(x2; b23x3)2 net (of x3) covariation between y and x2 net (of 3) variation in x2
