Model BayesianAveraging方法及其应用 潘海涛 (西安:西安财经学院统计学院,710061) 摘要 一般的回归分析建模因为未考虑模型自身的不确定性而使得分析的结果存在不精确和有 争议的问题,贝叶斯模型平均法(BayesianMovingAveraging)由于运用Bayes统计分析的 思想并考虑到模型自身的不确定性,从而提高了模型估计的精度。本文通过介绍...
Model Selection中,Frequentist试图找到一个Model,它避免overfitting的方法是用Validation set;而Bayesian则对in consideration的所有Models做weighted averaging,所用weights就是各个Model的posterior p(Mi|D),因此对于Bayesian来说,应该叫Model Averaging或Model Comparison而不是Model Selection。奇妙的是,这种weighted averaging...

In this R package problems of Bayesian model selection and model averaging are addressed in various complex regression contexts. The approaches developed within the package are based on the idea of marginalizing out parameters from the likelihood. This allows to work on the marginal space of models...

In this paper, objective Bayesian methods for hypothesis testing and variable selection in linear models are considered. The focus is on BayesVarSel, an R package that computes posterior probabilities of hypotheses/models and provides a suite of tools to properly summarize the results....
Bayesian statistics is an approach to data analysis based on Bayes’ theorem, where available knowledge about parameters in a statistical model is updated with the information in observed data. The background knowledge is expressed as a prior distributio
