| 摘 要： | 泊松分布和负二项分布常用于拟合保险索赔次数,和二项分布,几何分布统称为(a,b,0)分布族.讨论了(a,b,0)分布族中各个分布的性质及其相互关系,基于(a,b,0)分布族的性质,最后结合了我国某保险公司的索赔次数数据进行了实证分析,拟合了索赔次数分布.

| Abstract: | Abstract: Poisson and negative binomial distributions are usually used to fit claim frequencies. The two discrete distributions and binomial distribution totally constitute a class of discrete non-negative integer-valued distributions called (a,b,0)family. This paper discuss properties of (a,b,0) family. Finally, base on these properties, we apply the method on real claim frequency data from some domestic insurer and make a simulative study on distribution. |
