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. … Tīmeklis2024. gada 10. apr. · Calyampudi Radhakrishna Rao, a well-known Indian-American mathematician and statistician, will receive the 2024 International Prize in Statistics, the field's equivalent of the Nobel Prize.
