Abstract

This monograph is based on my CBMS-NSF lectures in August, 1991 at Chapel Hill, North Carolina. The flow of the chapters mirrors the flow of the lectures. While I have rearranged the material I distributed during the lectures, I have not added or deleted very much, except for adding remarks or details by way of clarification or resolution of issues raised by my very lively audience at Chapel Hill.

Most of the material is taken from my own work done jointly with many students and friends. One of the pleasures of lecturing or writing about all this has been the reliving of that experience of working and discovering together. My tastes and beliefs have evolved over time; some of that is reflected here too. Higher order asymptotics itself, like all mathematical tools, is philosophically neutral, and can be effectively used by both Bayesians and frequentists. The frequentist results here concentrate on optimality, but the theory can, in principle, be applied to parametric robustness studies also. I first learnt this from Kei Takeuchi. However, neither he nor I have followed this up. I hope someone else will. There are also open questions regarding noninformative priors, application of the new likelihoods to Neyman-Scott problems, higher order admissibility and minimaxity and Edgeworth expansions.
