Question 2. A linear regression model is given by where &; is the error term with E(&;) = 0 and Var(;) = ² for all i = 1, .., n. • The model can be expressed as where Yi = Bo + Bixi + B2x2+…+ Ppript&, i=1,…,n Find E(B) and Var(B). Y = X12 -0-30-0 ,X = 1 1 Y = XB + ε 1 • Derive the OLS estimator of ß, say , using the following objective function: = L(B) = arg min ||Y - XB||² and Question 2.
