If the errors in the classical linear regression model are NOT normally distributed is the OLS estimator still "BLUE"? Please explain why, or why not.

Expert Solution

the answer is true. The assumption of normally distributed errors in the classical linear regression model is required for hypothesis testing and producing reliable confidence intervals and prediction intervals. A violation of this assumption does not lead to biased estimates or an increase in the variance and thus the OLS estimates remain the best linear unbiased estimators (BLUE)

The variance of the error term is the same for all values of x. c. The values of the error term are independent. d.

When we estimate a linear multiple regression model (including a linear simple regression model), it appears that the calculation of the coefficient of determination, R2, for this model can be accomplished by using the squared sample correlation coefficient between the original values and the predicted values of the dependent variable of this model. Is this statement true? If yes, why? If not, why not? Please use either matrix algebra or algebra to support your reasoning.
