UEND 和φ混合随机变量随机和的精确大偏差
Precise large deviations for random sum of UEND andφ-mixing random variables
摘要
Abstract
The UEND andφ-mixing dependent random variables are introduced,and the issue of tail probability of random sum of UEND andφ-mixing random variables is investigated.By using a method of the precise large deviation of random sum of dependent random variables,the asymptotic behavior of random sum of heavy-tailed random variables is obtained.The conclusions are extended from independent non-identical distributed random variables to dependent and non-identical distributed random variables.关键词
