PROOF of the Gauss-Markov Theorem

Econometrics is the application of mathematics and statistics to analyze economic theory or economic phenomena. This subject delves into all you need to know about regression analysis and modeling - using cross-sectional, time series or panel data. *************************************************************************** This video lesson proves the Gauss-Markov theorem for the regression coefficients. It proves that the regression slope and intercept coefficients are/have: 1. Linear (linear function of the dependent variable) 2. Unbiased (expected values of the estimate equals the population parameter) 3. Minimum Variance (efficient estimators) To access the PDF file of the presentation, go to the repository for the course on my GitHub Page, and download the file from the folder named "PDF Presentation Files".
