摘 要:
设{xn,n≥1}是同分布的两两NQD列,记Sn=∑i=1Xi^n.本文讨论了max |Si|/i(n≥1)的分布函数的上下界.作为应用,获得了随机变量supn≥|Sn|/n型的1阶矩及p(〉1)阶矩分别存在有限的充分必要条件,这是一个与独立同分布场合相一致的结果.[著者文摘]

Abstract:
Let {Xn ,n≥1} be a sequence of identically distributed pairwise NQD random variables and Sn =∑^ni=1Xi(n≥1). The paper discusses the upper and lower bounds of the distribution function of max1≤i≤n |si|/i(n≥1). As its application, the sufficient and necessary conditions of the 1-th and p -th ( p 〉 1) moments of sup n≥1|sn|n are obtained, which are the same as the case of the independent identically distributions.[著者文摘]
