WebNov 28, 2024 · MLE is popular for a number of theoretical reasons, one such reason being that MLE is asymtoptically efficient: in the limit, a maximum likelihood estimator achieves minimum possible variance or the Cramér–Rao lower bound. Recall that point estimators, as functions of X, are themselves random variables. Web1 Efficiency of MLE Maximum Likelihood Estimation (MLE) is a widely used statistical estimation method. In this lecture, we will study its properties: efficiency, consistency … WebThe observed Fisher Information is the negative of the second-order partial derivatives of the log-likelihood function evaluated at the MLE.
