在本文中，我们开发了一个面板数据负二项计数模型，纠正内生分层和截断。我们还将一个潜在的类结构到我们的面板规格，它假设的意见是从有限数量的段，其中分布不同的截距和解释变量的系数。本文认为，计数数据面板模型校正现场抽样可能仍然是不够的，并可能产生误导，如果感兴趣的人口是异质性方面的影响所选择的解释变量。(JEL问题51、问题57）
In this paper, we develop a panel data negative binomial count model that corrects for endogenous stratification and truncation. We also incorporate a latent class structure into our panel specification, which assumes that the observations are drawn from a finite number of segments, where the distributions differ in the intercept and the coefficients of the explanatory variables. The paper argues that count data panel models corrected for on-site sampling may still be inadequate and potentially misleading if the population of interest is heterogeneous with respect to the impact of the chosen explanatory variables.
