自正则Chung型重对数律的精确渐近性
Precise Asymptotics in Chung’s Law of the Iterated Logarithm via Self-normalization
【摘要】 设X,X1,X2,…为零均值、非退化、吸引域为正态吸引场的独立同分布随机变量序列,记Sn=■Xj,Mn=■|Sk|,Vn2=■Xj2,n≥1.证明了当b>-1时,■δ-2(b+1)■(log log n)P/(n log n)P(Mn/Vn≤επ2/(8lgo log n)1/2) =4/πГ(b+1)■-1k/(2k+1)2b+3.
【Abstract】 Let X,X1,X2,...be i.i.d,nondegenerate random variables with zero means, Sn=■Xj,Mn=■|Sk|and Vn2=■Xj2 for n≥1.For b>-1,the authors show that ■ε-2(b+1)■((log log n)b)/(nlogn)p(Mn/Vn≤ε(π2/(8log log n)1/2) =4/πГ(b+1)■(-1)k/(2k+1)2b+3, when X belongs to the domain of attraction of the normal law.
