令{Xk;k≥1}为一列实值随机变量,{θk;k≥1}为另一列与之独立的随机变量序列.假设{Xk;k≥1}为两两广义负象限相依且服从重尾分布,在{θk;k≥1}独立和相依条件下,本文得到了一些渐近估计。
Let {Xk;k ≥ 1} be a sequence of real-valued random variables and {θk;k ≥ 1} be other n random variables which are independent of the form sequence.Suppose that {Xk;k≥ 1}are pairwise generalized negatively orthant dependent with heavy tails under the condition that{θk;k ≥ 1} are independent or associated,some asymptotic formulas are established.
