利用信度理论的方法,建立了Bayes聚合风险的信度模型,得到未来年总索赔的信度保费.进一步地,在多合同模型下,提出了结构参数的无偏估计,并证明了这些估计的统计性质.
The credibility premium of aggregate claim in Bayes collective risk model are derived based on the credibility theory.Moreover,in the models of multitude contract data,the corresponding unbiased estimators are suggested for the unknown structure parameters.And some statistical properties of those estimators are proved.
