"WebThe general theorem was formulated by Fisher [2]. The first attempt at a rigorous proof is due to Cramer [1]. A serious weakness of Cramer's proof is that, in effect, he assumes that the maximum likelihood estimator is consistent. (To be precise, he proves the theorem for the subclass of maximum likelihood estimators that are consistent. " - Fisher theorem

WebThe extreme value theorem (EVT) in statistics is an analog of the central limit theorem (CLT). The idea of the CLT is that the average of many independently and identically distributed (iid) random variables converges to a normal distribution provided that each random variable has finite mean and variance.
