A Central Limit Theorem under Contiguous Alternatives
邻接备择下的中心极限定理
In the statistical literature Le Cam's third lemma (cf. Hajek and Sidak (1967), page 208) is extensively used in order to get asymptotic normality of a statistic $S_n$ under contiguous alternatives from asymptotic normality of $S_n$ under the nullhypothesis. Since Le Cam's lemma utilizes the joint asymptotic normality of $S_n$ and $\log$-likelihood-ratio $\log L_n$, which is a sufficient but in general not a necessary condition for contiguity, it is not possible to get…
