一致最大功效贝叶斯检验

Uniformly most powerful Bayesian tests

Valen E. Johnson

摘要:

一致最大功效检验是在给定大小的所有检验中针对固定原假设提供最大功效的统计假设检验。在这篇文章中,一致最大功效检验的概念被扩展到贝叶斯设置,通过定义一致最大功效贝叶斯检验是最大化有利于备择假设的贝叶斯因子超过指定阈值的概率的检验。像他们的经典对应,一致最强大的贝叶斯检验是最容易定义的单参数指数族模型,虽然扩展以外的这一类是可能的。一致最大功效检验和一致最大功效贝叶斯检验之间的联系可用于提供p值和贝叶斯因子之间的近似校准。最后,讨论了贝叶斯因子和p值对样本量的强依赖性问题。

英文摘要:

Uniformly most powerful tests are statistical hypothesis tests that provide the greatest power against a fixed null hypothesis among all tests of a given size. In this article, the notion of uniformly most powerful tests is extended to the Bayesian setting by defining uniformly most powerful Bayesian tests to be tests that maximize the probability that the Bayes factor, in favor of the alternative hypothesis, exceeds a specified threshold. Like their classical counterpart, uniformly most powerful Bayesian tests are most easily defined in one-parameter exponential family models, although extensions outside of this class are possible. The connection between uniformly most powerful tests and uniformly most powerful Bayesian tests can be used to provide an approximate calibration between p-values and Bayes factors. Finally, issues regarding the strong dependence of resulting Bayes factors and p-values on sample size are discussed.
