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. Therefore, a low-variance estimator θ ... WebIn mathematical statistics, the Fisher information is a way of measuring the amount of information that an observable random variable X carries about an unknown parameter θ of a distribution that models X. Formally, it is the variance of the score, or the expected value of the observed information. The role of the Fisher information in the asymptotic …
