单向随机效应模型的Bayes因子相合性

Bayes Factor Consistency for One-way Random Effects Model

Min Wang, Xiaoqian Sun

摘要:

本文研究平衡单向随机效应模型的贝叶斯假设检验问题。一个特殊的选择的方差分量的比例的先验公式,产生一个明确的封闭形式的贝叶斯因子,而无需积分表示。此外,我们研究的一致性问题,由此产生的贝叶斯因子下三个渐近的情况:无论是单位的数量走向无穷大,每单位的观测数走向无穷大,或两者都走向无穷大。最后,所提出的方法的行为说明了仿真研究。

英文摘要:

In this paper, we consider Bayesian hypothesis testing for the balanced one-way random effects model. A special choice of the prior formulation for the ratio of variance components is shown to yield an explicit closed-form Bayes factor without integral representation. Furthermore, we study the consistency issue of the resulting Bayes factor under three asymptotic scenarios: either the number of units goes to infinity, the number of observations per unit goes to infinity, or both go to infinity. Finally, the behavior of the proposed approach is illustrated by simulation studies.
