Approximating Probability Densities by Iterated Laplace Approximations

open access: yes, 2011
The Laplace approximation is an old, but frequently used method to approximate integrals for Bayesian calculations. In this paper we develop an extension of the Laplace approximation, by applying it iteratively to the residual, i.e., the difference ...
