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 ...
