因此，栅栏模型可认为是二分类回归模型和零截尾计数模型的联合。
Therefore, the Hurdle model can be considered the combination of binary regression model and the zero-truncated count model.
文中第一部分阐述了零截尾计数模型的原理、参数估计及其模型应用。
The first chapter of the article introduced the principle of zero-truncated count model, parameter estimation and model application.
采用零截尾计数模型分析，不仅可以解决零截尾计数分布问题，且参数估计结果更准确，拟合效果更合理。
Zero-truncated count model could not only solve the issue of zero-truncated count distribution, but also the parameter estimates were more accurate, the fitting results were more reasonable.
