Bayesian model averaging (BMA) is a statistical method to rigorously take model uncertainty into account. This chapter gives a coherent overview on the statistical foundations and methods of BMA and its usefulness for forecasting, but also for the identification of robust determinants. The focus is ...

The purpose of this study is to adopt the Bayesian model averaging (BMA) based on linear regression models and to determine the predictors of the LOHS of COVID-19. Methods In this historical cohort study, from 5100 COVID-19 patients who had registered in the hospital database, 4996 ...
Thus, the family of all ADGs with a given set of vertices is naturally partitioned into Markov-equivalence classes, each class being associated with a unique statistical model. Statistical procedures, such as model selection or model averaging, that fail to take into account these equivalence ...
We propose Bayesian model averaging (BMA) as a method for postprocessing the results of model-based clustering. Given a number of competing models, appropriate model summaries are averaged, using the posterior model probabilities, instead of being taken from a single "best" model. We demonstrate ...
Paper 242-2017 Random Forests with Approximate Bayesian Model Averaging Tiny du Toit, North-West University, South Africa; André de Waal, SAS Institute Inc. ABSTRACT A random forest is an ensemble of decision trees that often produce more accurate results than a single decision tree. The ...
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...
