摘要
令{X,Xi:i≥1)为属于非退化稳定分布一般吸引场的独立同分布随机变量列,Sn=∑i=1nXi.本文对十分广泛的拟权函数和边界函数得到了Sn的精致渐近的结果和正态吸引场强平稳NA列部分和的精致渐近的结果,改进并推广了Wang等的结果,从而使此前关于独立列和NA列部分和精致渐近性方面的许多经典的和最新的结果都可以包括在本文的框架之内.
Let {X, Xi : i ≥ 1} be a sequence of iid random variables which belongs to the domain of attraction of a nondegenerate stable distribution and let Sn = ∑i=1n Xi. A result on the precise asymptotics of Sn for wide range weighted functions and boundary functions is obtained. The results of precise asymptotics of partial sums for strictly stationary NA sequence are obtained. The results in Wang etc. are improved and extended. Many important results from the literatures are obtained easily as corollaries.
