  • We consider evaluation of proper posterior distributions obtained from improper prior distributions. Our context is estimating a bounded function Φ of a parameter when the loss is quadratic. If the posterior mean of 0 is admissible for all bounded Φ, the posterior is strongly admissible. We give sufficient conditions for strong admissibility. These conditions involve the recurrence of a Markov chain associated with the estimation problem. We develop general sufficient conditions for recurrence… CONTINUE READING
