Abstract:

This article reviews some second-order approximations to the posterior mean, and the marginal distribution of observations called a marginal likelihood, where “second-order” means that the approximation has asymptotic errors of order $O(n^{-2})$ as the sample size $n$ goes to infinity. In addition, the Laplace approximations using asymptotic modes instead of the exact mode of integrand, and higher-order asymptotic expansions are presented.
