经验似然与贝叶斯MAP的渐近等价性

Asymptotic equivalence of empirical likelihood and Bayesian MAP

Marian Grendár, George Judge

摘要:

在本文中,我们感兴趣的经验似然(EL)作为一种估计方法,我们解决了以下两个问题:(1)选择在EL框架中的各种经验差异和(2)证明,EL有一个定义良好的概率解释,将证明其使用在贝叶斯上下文中。使用大偏差的方法,贝叶斯大数定律的发展,这意味着EL和贝叶斯最大后验概率(MAP)估计是一致的误设定和EL可以被看作是一个渐近形式的MAP。基于其他经验差异的估计,在一般情况下,不一致的误指定。

英文摘要:

In this paper we are interested in empirical likelihood (EL) as a method of estimation, and we address the following two problems: (1) selecting among various empirical discrepancies in an EL framework and (2) demonstrating that EL has a well-defined probabilistic interpretation that would justify its use in a Bayesian context. Using the large deviations approach, a Bayesian law of large numbers is developed that implies that EL and the Bayesian maximum a posteriori probability (MAP) estimators are consistent under misspecification and that EL can be viewed as an asymptotic form of MAP. Estimators based on other empirical discrepancies are, in general, inconsistent under misspecification.
