考察了复合更新风险模型的精细大偏差。单次事故导致的索赔额为广义负上象限相依的且服从重尾分布的随机变量,单次事故引起的总索赔额与其对应的索赔时间间隔相依。
The precise large deviations for a compound renewal risk process were considened.The claim sizes related to one accident are heavy-tailed distributed random variables with extend negatively upper orthant dependence ( ENUOD) structure.The aggregate amount of claims and the inter-accident times correspondingly obeys a dependence structure.
