Right-censored Poisson Regression Model

Abstract

I present the rcpoisson command for right-censored count-data models with a constant (Terza 1985, Economics Letters 18: 361–365) and variable censoring threshold (Caudill and Mixon 1995, Empirical Economics 20: 183–196). I show the effects of censoring on estimation results by comparing the censored Poisson model with the uncensored one.
