1. MLR.6 Normality In the following table, check the boxes to indicate the assumptions for (1) OLS estimators to be unbiased, for (2) OLS estimators to be BLUE, and for (3) OLS estimators to be the minimum variance unbiased estimators. Assumption MLR.1 Linear in parameters MLR.2 Random sampling MLR.3 No perfect collinearity MLR.4 Zero conditional mean (of error term) MLR.5 Homoskedasticity MLR.6 Normality (of error term) Unbiased OLS Estimators (1) BLUE OLS Estimators (2) Minimum Variance Unbiased OLS Estimators (3)
