Econometrics: What is the Gauss Markov Theorem?
According to the Gauss Markov Theorem, if the first six classical assumptions are met within your model, then the estimates produced by Ordinary Least Squares will be BLUE. This means that Ordinary Least Squares will produce the Best Linear Unbiased Estimates available. Hence, BLUE. Check out our blogs on the classical assumptions here. So what exactly …
