Consider the simple regression y; : g + 311::- + (5;. The Gauss-Markov conditions hold. Suppose g and 61 are estimates of g and {31 respectively. Show that the error sum of squares using these new estimates is equal to 23:1 E? + 23:1 [an ,5") + [61 5.1:!1171'] 2, where e.- is the ith residual usng the OLS estimates. What conclusion do we draw from this result
