摘要
非寿险精算中,索赔次数的分布一般假设为普阿松分布P(λ).风险非同质时的分布称为混合分布.该文考虑了混合分布为三参数伽玛分布时的参数估计以及位置参数的检验问题.
In non-life-insurance accuracy, the distribution of the damages-acclamation times λ is normally supposed as poisson distribution P(λ), which is also called mixed distribution in the case that risks are of different qualities. In this paper,the research on the parameter estimation of Gamma distribution with three parameters and the test of the location parameters has been made.
