NettetLehmann & Scheffe (1950, pp. 335-336) also obtain this t as a minimal sufficient statistic in their definition, but their method is complicated. We cannot apply the method by Barndorff-Nielsen et al. (1975) to this example. O 3.

These are contributions of the mid 1950s. I cannot offer you an intuitive explanation - but if you really want to build one, maybe the proofs associ $\endgroup$ –

Then, if is unbiased, is the unique UMVU. We will define what it means for a statistic to be complete soon. A question that immediately arises is whether UMVU estimators are always unique. The answer is yes, they are.
NettetIn fact, since S n is complete and δ 0 is unbiased, δ 1 is the unique minimum variance unbiased estimator by the Lehmann–Scheffé theorem. Idempotence. Rao–Blackwellization is an idempotent operation. Using it to improve the already improved estimator does not obtain a further improvement, but merely returns as its output the … NettetThe Lehmann-Scheffé Theorem. Theorem: If S is a complete sufficient statistic for some model and h(S) is an unbiased estimate of some parameter then h(S) is the UMVUE of . Proof: Suppose T is another unbiased estimate of .
