标题： Bayesian finite mixtures: a note on prior specification and posterior computation

摘要： 提出了一种计算有限混合分布中分量个数k的后验分布的新方法。还研究了先验设定的两个方面：论证了在k的先验分布中使用Poisson(1)分布；给出了在具有分量参数自然共轭先验的正态混合模型中选择超参数值的方法。 显示英文摘要

摘要： A new method for the computation of the posterior distribution of the number k of components in a finite mixture is presented. Two aspects of prior specification are also studied: an argument is made for the use of a Poisson(1) distribution as the prior for k; and methods are given for the selection of hyperparameter values in the mixture of normals model, with natural conjugate priors on the components parameters.
