Analysis of Variance ˆ s β Elasticities – another interpretation of results. • Elasticity – the % change in quantity due to a 1% change in price, or income. • From micro: • For the estimated regression model: E. Properties of OLS Estimators 1. Linear: The OLS estimators are still linear estimators. 2. Unbiased: If CRMAs # 1 – 3 are correct, the OLS estimators are unbiased estimators. 3. Minimum Variance: If CRMAs # 1 – 5 are correct, the OLS estimators are the Best Linear Unbiased Estimators. (Gauss-Markov Theorem) Draw a graph illustrating properties 2 & 3. 2 F.
