Linear statistics in change-point estimation and their asymptotic behaviour
Authors:A L Rukhin
Abstract:ABSTRACT The limiting behaviour of Bayes procedures in the asymptotic setting of the change-point estimation problem is studied. It is shown that the distribution of the difference between the Bayes estimator and the parameter converges to the distribution of a fairly complicated random variable. A class of linear statistics is introduced, and the form of the Bayes estimator within this class is deduced. The asymptotic properties of this linear estimator are investigated in two different settings for the prior distribution.
Keywords:Bayes risk  change-point problem  integral operator  linear estimator  prior distribution  quadratic loss
