Blue property assumptions

WebA property which is less strict than efficiency, is the so called best, linear unbiased estimator (BLUE) property, which also uses the variance of the estimators. ... Finite sample properties try to study the behavior of an estimator under the assumption of having many samples, and consequently many estimators of the parameter of interest. Thus ... The Gauss-Markov theorem famously states that OLS is BLUE. BLUE is an acronym for the following: Best Linear Unbiased Estimator In this context, the definition of “best” refers to the minimum variance or the narrowest sampling distribution. More specifically, when your model satisfies the assumptions, OLS … See more Regression analysis is like any other inferential methodology. Our goal is to draw a random sample from a population and use it to estimate the properties of that population. In … See more Imagine that we repeat the same study many times. We collect random samples of the same size, from the same population, and fit the same OLS regression model … See more As you can see, the best estimates are those that are unbiased and have the minimum variance.
