信息冲突下的后验何时渐近正态？AI 解读

When data conflicts with quantified prior beliefs, seemingly small changes in the functional form of the prior and/or likelihood can have a profound effect on posterior inferences. This article provides results on asymptotic forms of the posterior when two information sources conflict. In particular, let x be from the likelihood p 2(x − θ) with an unknown location parameter θ, with p 1(θ) the prior on θ. Sufficient conditions on p 1 and p 2 are provided to ensure that as x →…
