5. Suppose the intercept of simple linear regression model is known as 5. One can consider the model Y = 5+3X +ui for i = 1,..., n, E(ui) = 0, Var(ui) = 1. Find the OLS estimator , EC), Var(@). 6. Consider the simple linear regression given by Y = B1 + B2X: +ui But instead of assuming E( X) = 0 for i = 1,..., n, suppose one assume E(ui|X) = 3. Obtain OLS estimator 1, B2. 5.
