Let µ^ = r(X 1;¢¢¢ ;Xn) = r(X) be an arbitrary estimator of µ. Assume Eµ(µ^) = m(µ), and the variance of µ^is flnite. Let us consider the random variable l0 n(Xjµ) deflned in (4), it was shown in (5) that Eµ[l0 n(Xjµ)] = 0.

WebNov 28, 2024 · An UMVUE (Unformly Minimum Variance Unbiased Estimator) rarely attains the CRLB. Moreover: if a family of rv's belongs to the exponential family (as it is the case) always exist an estimator that attains CRLB. To verify that an estimator attains the lower bound there is a IFF condition: WebThe lower bound is the smallest value that would round up to the estimated value.
