不可忽略结局缺失下强化识别的广义线性模型估计

研究问题
当结局是否被观察依赖未观测变量时,如何识别并估计广义线性结局模型,同时减少对难以确定的工具变量的依赖?
方法与思路
作者在逻辑回归响应机制与广义线性结局模型下,对可观测部分建模并推导识别充分条件,另提出实践指引和敏感性分析。
材料陈述的贡献
摘要称所推导的识别充分条件无需工具变量,并以数值研究、韩国选举出口民调及家庭调查数据展示估计方法。
阅读关注点
应核对响应模型和结局模型的具体识别条件、模型误设风险,以及实践指引和敏感性分析如何约束不可观察的缺失机制。
阅读边界
这是 arXiv 预印本,同行评审及期刊接收未核实;无需工具变量仍依赖模型限制,摘要未列出充分条件及误设下保证。

原文摘要

Missing data often result in undesirable bias and loss of efficiency. These issues become substantial when the response mechanism is nonignorable, meaning that the response model depends on unobserved variables. To manage nonignorable nonresponse, it is necessary to estimate the joint distribution of unobserved variables and response indicators. However, model misspecification and identification issues can prevent robust estimates, even with careful estimation of the target joint distribution. In this study, we modeled the distribution of the observed parts and derived sufficient conditions for model identifiability, assuming a logistic regression model as the response mechanism and generalized linear models as the main outcome model of interest. More importantly, the derived sufficient conditions do not require any instrumental variables, which are often assumed to guarantee model identifiability but cannot be practically determined beforehand. To analyze missing data in applications, we propose practical guidelines and sensitivity analysis to determine the response mechanism. Furthermore, we present the performance of the proposed estimators in numerical studies and apply the proposed method to two sets of real data: exit polls from the 19th South Korean election and public data collected from the Korean Survey of Household Finances and Living Conditions.
