A Bayesian Variation of Basu’s Theorem and its Ramification in Statistical Inference

Research output: Contribution to journalArticlepeer-review

Abstract

One of the celebrated results of Professor D. Basu is his 1955 paper on ancillary statistics, which established the well known Basu’s Theorem. A Bayesian version of this result, where the parameter Θ is treated as a random variable, is developed in this note, along with other extensions of the related classical results, such as Rao-Blackwell and Lehmann-Scheffé theorems and the relation between complete sufficiency and minimal sufficiency. These extensions shed new light on these fundamental theorems for frequentist statistical inference in the context Bayesian inference.
