Statistical analysis of finite mixture distributions
TL;DR: This course discusses Mathematical Aspects of Mixtures, Sequential Problems and Procedures, and Applications of Finite Mixture Models.
Journal ArticleDOI
Deviance information criteria for missing data models
TL;DR: The deviance information criterion is reassessed for missing data models, testing the behaviour of variousextensions in the cases of mixture and random models.
Journal ArticleDOI
Asymptotically optimal difference-based estimation of variance in nonparametric regression
TL;DR: In this article, the authors define and compute asymptotically optimal difference sequences for estimating error variance in homoscedastic nonparametric regression, and provide substantial improvements over the suboptimal sequences commonly used in practice.
Journal ArticleDOI
A study of methods of choosing the smoothing parameter in image restoration by regularization
TL;DR: The method of regularization is portrayed as providing a compromise between fidelity to the data and smoothness, with the tradeoff being determined by a scalar smoothing parameter.

TL;DR: In this paper, a hierarchical prior model is proposed to deal with weak prior information while avoiding the mathematical pitfalls of using improper priors in the mixture context, and a sample from the full joint distribution of all unknown variables is generated, which can be used as a basis for a thorough presentation of many aspects of the posterior distribution.
