Blackwell's theorem
WebBy factorization theorem, we show that X ( 1) is a sufficient statistical for θ. And, since. E ( X) = θ + 1. the estimator X ¯ − 1 is unbiased. So, by the Rao Blackell theorem, W = E ( X ¯ − 1 ∣ X ( 1)) is an unbiased estimator that is function of the sufficient statistical. But it seems very complicated to evaluate the distribution ... WebFollowing the same authors, the theorem says: (Theorem: Blackwell's sufficient condition for a contraction.) Let X ⊂ R l and let B ( X) be a space of bounded functions f: X → R …
