What Is Unbiased Estimates? Minimum Variance Estimates? Gauss Markov Theorem. (1) What Is Gauss Markov Theorem? The Gauss-Markov theorem states that if your linear regression model satisfies the first six classical assumptions, then ordinary least squares (OLS) regression produces unbiased estimates that have the smallest variance of all possible linear estimators. If our Linear Regression model satisfies the firs six classical assumptions, then the estimators are said to be ‘BLUE’. (2) What Are ‘BLUE’ Estimators? BLUE
