WebFor fixed f f the maximum-likelihood estimate (MLE) is well-known to be optimal in the limit as n → ∞ n → ∞: it is asymptotically normal with variance matching the Cramer-Rao lower bound of 1 nI 1 n I, where I I is the Fisher information of f f. However, this bound does not hold for finite n n, or when f f varies with n n. We show for ... Webfor nding the MLE (so that it is already available without extra computation).

Webmaximum). In machine learning/data science, how to numerically nd the MLE (or approximate the MLE) is an important topic. A common solution is to propose other computationally feasible estimators that are similar to the MLE and switch our target to these new estimators. 3.3 Theory of MLE The MLE has many appealing properties.
