摘要

本文将两参数离散威布尔分布与第一类Beta分布复合，引入一种新的离散模型。该模型可以在特定参数设置下嵌套到不同的复合分布中。该模型是一个很好的竞争零膨胀模型。此外，我们给出了新分布的基本性质，并讨论了单峰性、故障率函数和色散指数。最后，该模型与现实生活中来自医学科学的计数数据进行检验，以调查所提出的模型的适用性。

An Advanced Discrete Model with Applications in Medical Science

In this paper, we introduce a new discrete model by compounding two parameter discrete Weibull distribution with Beta distribution of first kind. The proposed model can be nested to different compound distributions on specific parameter settings. The model is a good competitive for zero-inflated models. In addition, we present the basic properties of the new distribution and discuss unimodality, failure rate functions and index of dispersion. Finally, the model is examined with real-life count data from medical sciences to investigate the suitability of the proposed model.
