摘要
设{Xn;n≥1}是独立同分布的且服从标准正态分布的随机变量序列,{Sn,n≥1}是其部分和数列,本文讨论了它的特殊的有限加权部分和数列{ Sn,n≥1}的重对数律,其中 Sn=α1Sn+α2(S2n-Sn)+α3(S3n-S2n)+…+αd(Sdn-S(d-1)n),把Hartman-Wintner重对数律推广到对特殊加权部分和也成立.
Let be mutually independent random variables, identically distributed according to the normal distribution, be finite partial sum series, the purpose of this paper is to investigate law of the iterated logarithm type results for special finite partial weight sum series,we assume that .
