经验贝叶斯方法的有限样本推断

Finite sample inference for empirical Bayesian methods

Hien D Nguyen, Mayetri Gupta

摘要:

近年来,经验贝叶斯(EB)推理已成为一个有吸引力的方法,估计参数模型中出现的各种现实生活中的问题,特别是在复杂和高维的科学应用。然而,相对丰富的可用的一般方法来计算点估计在EB框架中,建设的置信集和假设检验具有良好的理论性质仍然是困难的和具体的问题。受Wasserman等人(2020)的通用推理框架的启发,我们提出了一种通用的方法,基于保持似然比,并利用指定贝叶斯模型的层次结构来构建有限样本有效的置信集和假设检验。我们说明我们的方法,通过一系列的数值研究和实际数据的应用,这表明该方法是能够产生有用的和有意义的推理语句在相关的上下文中。

英文摘要:

In recent years, empirical Bayesian (EB) inference has become an attractive approach for estimation in parametric models arising in a variety of real-life problems, especially in complex and high-dimensional scientific applications. However, compared to the relative abundance of available general methods for computing point estimators in the EB framework, the construction of confidence sets and hypothesis tests with good theoretical properties remains difficult and problem specific. Motivated by the universal inference framework of Wasserman et al. (2020), we propose a general and universal method, based on holdout likelihood ratios, and utilizing the hierarchical structure of the specified Bayesian model for constructing confidence sets and hypothesis tests that are finite sample valid. We illustrate our method through a range of numerical studies and real data applications, which demonstrate that the approach is able to generate useful and meaningful inferential statements in the relevant contexts.
