本文研究了一类复合二项-负二项风险模型,并对所建立的模型,利用鞅分析方法讨论了模型的调节系数,推导了保险公司在初始准备金为U条件下的最终破产概率ψ(u)的表达式和Lundberg不等式。
This paper focused on one type of compound binomial - negative binomial risk model, discussed the adjustment factors by martingale and derived the final bankruptcy probability ψ(u) expression and Lundberg inequality when insurance companies' initial reserve is u.
