Abstract

Let (X(1), theta(1)), (X(2), theta(2)), ..., (X(N), theta(N)), (X(N+1), theta(N+1)) be independent random vectors with each theta(i) distributed according to some unknown prior density g. Given theta(i), let X(i) have the conditional density q(i)(x/theta(i)), i=1, ..., N+1. In each pair the first component is observable, but the second is not. The objective is to estimate a known function b(theta(N+1)) of theta(N+1). A general technique for construction of empirical Bayes estimators of b(theta(N+1)) is proposed and their convergence rates are examined. The special case, when the conditional densities q(i)(x/theta), i=1, ..., N+1, are identical, is also discussed. The theory is used to estimate of some reliability characteristics of nuclear power plant equipment.
