本文研究了截断样本计数数据的一类极大似然回归估计。截断泊松分布和负二项分布的估计进行了说明。仿真结果给出说明的偏差，可能会导致失败，以占截断样本的过度分散的幅度。提供了一个经验的应用程序的基础上采取的阿拉斯加渔民的样本休闲捕鱼旅行的数量。
This paper examines a class of maximum‐likelihood regression estimators for count data from truncated samples. Estimators for the truncated Poisson and negative binomial distributions are illustrated. Simulation results are given to illustrate the magnitude of the bias that may result from the failure to account for overdispersion in truncated samples. An empirical application based upon the number of recreational fishing trips taken by a sample of Alaskan fishermen is provided.
