摘要
在非寿险精算中 ,索赔次数的分布一般假设为泊松分布 P(λ) .风险非同质时 λ的分布称为混合分布 .
In the non\|life insurance, the distribution of the number of claim can be assumed as the Possion distribution P(λ). When the risk is inhomogeneous, the distribution of λ is called as mixed distribution. In this paper, parameter estimation and test will be considered when three\|parameter Γ distribution is taken as mixed distribution.
