Consider the regression model with the heterogeneous coefficient. Y₁ = Boi + BX, +%₂ where (v. X₁. Boi. Bu) are i.i.d random variables with Bo=E (Boi) and B₁ = E (Bu) It is possible to show that the model can be written as Y,= Bo + B,X, +u, where u, = (Boi-Bo) + (B₁-B₁) X1 + v And, it is also possible to show that E[u[X]-0 when we assume that E (Boi Xi) Bo. E (BulXi) B₁. and E (v₁|X₁) = 0. (you don't need to prove these results here.) Based on these results, we can conclude that under the current setting, regression of Y on X and an intercept will yield a consistent estimation of the ( ). Fill the parenthesis with three words. A
