潜在分组可能无法分离时面板模型的稳健推断

研究问题
在线性面板模型中,系数的潜在分组需要由数据估计且组间可能无法分离时,如何对一般线性限制作有效推断?
方法与思路
作者条件于数据估计的分组结构开展选择性推断,构造条件检验并反演得到置信集合,以纳入分组估计的不确定性。
材料陈述的贡献
摘要称已知方差的高斯误差下检验精确有效,一般误差下渐近有效,并在模拟及增长收敛俱乐部应用中展示效果。
阅读关注点
应核对分组算法对应的选择事件、条件分布的计算,以及一般误差、序列相关和截面依赖下有效性所需的具体条件。
阅读边界
这是 arXiv 预印本,同行评审与期刊接收未核实;精确有效性有明确误差和方差前提,摘要未说明一般情形的完整渐近条件。

原文摘要

We develop robust inference methods for general linear hypotheses in linear panel data models with latent group structure in the coefficients. We employ a selective conditional inference approach based on the conditional distribution of coefficient estimates given the group structure estimated from the data. The resulting inference procedures remain valid even when group separation fails (i.e., when the distributional properties of the group-specific coefficients are not established) and, because they account for uncertainty in estimating the group structure, they also improve on conventional asymptotic procedures in finite samples when separation does hold. Our tests are exactly valid under Gaussian errors with known variances and asymptotically valid under general error distributions. Unlike much of the post-clustering inference literature, which focuses on testing group homogeneity, our framework accommodates arbitrary linear restrictions on the group-specific coefficients. Inverting the conditional tests yields selective confidence sets with valid coverage conditional on the estimated group structure. We illustrate the methods through Monte Carlo simulations and an application to growth convergence clubs. Simulations demonstrate accurate size control and good power in finite samples, including in the presence of serial correlation and cross-sectional dependence. The applications show sharp differences between the traditional inference methods and robust methods proposed in this paper, illustrating the importance of taking the estimated group structure into account.
