上尾独立的不同分布的随机变量和的精确大偏差

摘要

The precise large deviation for bivariate upper tail independent and non-identical random variables with long tailed distributions was researched, Asymptotic relations for both the partial suns Sn and the random sums S(t) were obtained, which thus generalizes the results of Skucaite (2004).%主要研究了长尾上的带有二元上尾独立的、不同分布的随机变量和的精确大偏差，得到了随机和和非随机和的两种一致变化尾概率的结论，推广了Skucaite (2004)的相应结论。
