QUESTION 5 Gauss-Markov theorem states, that if the model for E(YIX) is correctly specified, and the four assumptions of the multiple regression model hold, then the estimators of the parameters of the regression equation have the smallest bias among all linear and unbiased estimators of the intercept and slope coefficients. Is it true or false? True O False QUESTION 6 Analysts should compare the Root MSE to the standard deviation of the dependent variable in order to judge the magnitude of the standard error of the regression, and it is true in the simple and multiple regression models. Is it true or false? True O False
