##### The point of this exercise is to show that tests for functional form cannot be relied on as a general test for omitted variables. Suppose that, conditional on the explanatory variables X and Xz, a linear model relating Y to Xp and Xz satisfies the Gauss-Markov assumptions: y Bo B1xi + Bxxz + V Elulx, Xz) =0 Var(ulrz, Xz) 0? To make the question interesting, assume Bz # 0. Suppose further that xz has a simple linear relationship with xj: X2 = 80 + 81X1 + r E(rkx) = 0 Var(rkx;) = +2 Show thatElylx
