缺失数据模型的Monte Carlo似然推断

Monte Carlo likelihood inference for missing data models

Yun Ju Sung, Charles J. Geyer

摘要:

当存在缺失数据且观测数据的似然性不能以封闭形式提供时,我们描述了一种近似最大似然估计(MLE)的蒙特卡罗方法。该方法使用独立同分布且独立于观测数据的模拟缺失数据。我们的蒙特卡罗近似的极大似然估计是一个一致的和渐近正态估计的最小值$θ^*$的Kullback-Leibler信息,蒙特卡罗和观测数据的样本量同时走向无穷大。插件估计的渐近方差提供构造置信区域$θ^*$。我们给出了Logit-正态广义线性混合模型的例子,使用R软件包计算。

英文摘要:

We describe a Monte Carlo method to approximate the maximum likelihood estimate (MLE), when there are missing data and the observed data likelihood is not available in closed form. This method uses simulated missing data that are independent and identically distributed and independent of the observed data. Our Monte Carlo approximation to the MLE is a consistent and asymptotically normal estimate of the minimizer $θ^*$ of the Kullback--Leibler information, as both Monte Carlo and observed data sample sizes go to infinity simultaneously. Plug-in estimates of the asymptotic variance are provided for constructing confidence regions for $θ^*$. We give Logit--Normal generalized linear mixed model examples, calculated using an R package.
