摘要:

{ξn,n1}是正的随机变量序列, \epξ1=θ>0, 设Sn=ni=1ξi,Yn=nθlog(Sn/(nθ)). 在该文中, 当{ξn}是独立同分布或强平稳φ -混合的正随机变量序列时,作者给出功率和{Yn}用Wiener过程的强逼近结果.

关键词: 功率和, 强逼近, Wiener过程

Abstract: Let {ξn,n1} be a sequence of positive random variables with \epξ1=θ>0, and Sn=nn=1ξi,Yn=nθlog(Sn/(nθ)). In this article, the author gives strong approximations of power sums {Yn} be Wiener
process when {ξn} is a sequence of independent identically disributed random variables or a sequence of φ-mixing stationary random variables.

Key words: Power sums, Strong approximation, Wiener process
