Nonparametric Bayesian methods for one-dimensional diffusion models
In this paper we review recently developed methods for nonparametric Bayesian
inference for one-dimensional diffusion models. We discuss different possible
prior distributions, computational issues, and asymptotic results
On nonparametric estimation of a mixing density via the predictive recursion algorithm
Nonparametric estimation of a mixing density based on observations from the
corresponding mixture is a challenging statistical problem. This paper surveys
the literature on a fast, recursive estimator based on the predictive recursion
algorithm. After introducing the algorithm and giving a few examples, I
summarize the available asymptotic convergence theory, describe an important
semiparametric extension, and highlight two interesting applications. I
conclude with a discussion of several recent developments in this area and some
open problems.Comment: 22 pages, 5 figures. Comments welcome at
