Linearity of OLS estimators | Unbiasedness of OLS estimators | Econometrics | Ecoholics

Note that OLS estimators are linear only with respect to the dependent variable and not necessarily with respect to the independent variables. The linear property of OLS estimators doesn't depend only on assumption A1 but on all assumptions A1 to A5.

Under the standard assumptions, the OLS estimator in the linear regression model is thus unbiased and efficient. No other linear and unbiased estimator of the regression coefficients exists which leads to a smaller variance. An estimator is unbiased if its expected value matches the parameter of the population.
