摘要:

该文讨论基于客户来到的二维风险模型.假设潜在索赔额$\overrightarrow{X^{i}}=(X_{1}^{i},X_{2}^{i})^{\top}$是独立同分布的随机向量序列,$X_{1}^{i}$$X_{2}^{i}$是相依的,在重尾分布族$C$下得到了损失过程部分和与随机和的精细大偏差.

Abstract:

In this paper, we discuss the two-dimensional risk model based on the entrance process. Assuming that $\overrightarrow{X^{i}}=(X_{1}^{i}, X_{2}^{i})^{\top}$ is a two-dimensional random vector sequence with the same distribution, $X_{1}^{i}$ and $X_{2}^{i}$ are dependent, and the precise large deviation between the partial sum and the random sum of loss precess is obtained under the heavy tail distribution family C.

Key words: Insurance risk model, Precise large deviations, Two-dimensional, C class, Copula funtions
