Convergence rates of posterior distributions

We consider the asymptotic behavior of posterior distributions and Bayes estimators for infinite-dimensional statistical models. We give general results on the rate of convergence of the posterior…
POSTERIOR CONSISTENCY OF DIRICHLET MIXTURES IN DENSITY ESTIMATION

A Dirichlet mixture of normal densities is a useful choice for a prior distribution on densities in the problem of Bayesian density estimation. In the recent years, efficient Markov chain Monte Carlo…
Convergence rates of posterior distributions for non-i.i.d. observations
- S. Ghosal, A. V. D. Vaart
- Mathematics
- 1 February 2007
We consider the asymptotic behavior of posterior distributions and Bayes estimators based on observations which are required to be neither independent nor identically distributed. We give general…
Entropies and rates of convergence for maximum likelihood and Bayes estimation for mixtures of normal densities
- S. Ghosal, A. V. D. Vaart
- Mathematics
- 1 October 2001
We study the rates of convergence of the maximum likelihood estimator (MLE) and posterior distribution in density estimation problems, where the densities are location or location-scale mixtures of…
Convergence rates for density estimation with Bernstein polynomials
- S. Ghosal
- Mathematics
- 1 October 2001
Mixture models for density estimation provide a very useful set up for the Bayesian or the maximum likelihood approach. For a density on the unit interval, mixtures of beta densities form a flexible…

TESTING MONOTONICITY OF REGRESSION By
- S. Ghosal
- Mathematics
- 1998
We consider the problem of testing monotonicity of the regression function in a nonparametric regression model. We introduce test statistics that are functionals of a certain natural U-process. We…
Adaptive Bayesian inference on the mean of an infinite-dimensional normal distribution
- E. Belitser, S. Ghosal
- Mathematics
- 1 April 2003
We consider the problem of estimating the mean of an infinite-break dimensional normal distribution from the Bayesian perspective. Under the assumption that the unknown true mean satisfies a…
