[Solved] Finding the MVUE using Rao-Blackwell Theorem

TīmeklisThe Rao–Blackwell theorem and the essential uniqueness of the MVUE implies that A MVUE must essentially be a function of any minimal suﬃcient statistic. To see this, assume U is MVUE and let T be minimal suﬃcient. Then Rao–Blackwellize U to U∗ = E{U T}. We then have V(U∗) ≤ V(U), but as U was already MVUE, U∗ is also MVUE. … http://www.math.louisville.edu/~rsgill01/667/Lecture%209.pdf maybelline johnny rivers chords
