"Tīmeklis2024. gada 7. jūn. · the Rao–Blackwell–Kolmogorov theorem can be used for the construction of the best unbiased estimator for the distribution function $ \Phi ( ( x - \xi ) / \sigma ) $. As an initial statistic $ \phi $ one may use, e.g., the empirical distribution function constructed from an arbitrary component $ X _ {1} $ of $ X $: " - Rao blackwell umvue

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.stats.ox.ac.uk/~steffen/teaching/bs2siMT04/si3c.pdf
