WebSep 27, 2019 · Unbiasness is one of the properties of an estimator in Statistics. If the following holds, where $\hat {\theta}$ is the estimate of the true population parameter $\theta$: \ [E (\hat {\theta}) = \theta\] then the statistic $\hat {\theta}$ is unbiased estimator of the parameter $\theta$.

WebLet T(Y) be a complete suﬃcient statistic. If eg(T(Y)) is an unbiased estimator, then eg(T(Y)) is an MVUE. Proof. By Rao-Blackwell, if bg(Y) is an unbiased estimator, we can always ﬁnd another estimator eg(T(Y)) = E Y |T(Y)[bg(Y)]. (9) Since T(Y) is complete, eg(T(Y)) is unique. So it must be MVUE.
