Analysis of panel data is often challenged by the presence of heterogeneity and state misclassification. In this paper, we propose a hidden mover-stayer model to facilitate heterogeneity for a population that consists of two subpopulations each of movers or of stayers and to simultaneously account for state misclassification. We develop an inference procedure based on the expectation-maximization algorithm by treating the mover-stayer indicator and underlying true states as latent variables. We evaluate the performance of the proposed method and investigate the impact of ignoring misclassification through simulation studies. The proposed method is applied to analyze the data arising from the Waterloo Smoking Prevention Project. Copyright © 2017 John Wiley & Sons, Ltd.
面板数据的分析常常受到异质性和状态误分类的挑战。在本文中,我们提出了一种隐藏的流动者-留守者模型,以促进对由流动者或留守者两个亚群体组成的总体的异质性分析,并同时考虑状态误分类。我们通过将流动者-留守者指标和潜在真实状态视为潜在变量,基于期望最大化算法开发了一种推断程序。我们通过模拟研究评估了所提出方法的性能,并研究了忽略误分类的影响。所提出的方法被应用于分析滑铁卢预防吸烟项目产生的数据。版权所有© 2017约翰·威利父子有限公司。
