我们建立了关于I.I.D.的适当正规化部分和的增量的LIM超行为的非常一般的单边结果。随机变量。我们的主要结果适用于任意非退化正随机变量,它们不需要有任何有限矩。作为推论,我们可以证明这样的结果对于负值部分具有有限矩母函数的随机变量也是成立的。
We establish very general one-sided results on the lim sup behavior of increments of suitably normalized partial sums of i.i.d. random variables. Our main results apply to arbitrary nondegenerate positive random variables which need not have any finite moments. As a corollary we can show that such results also hold for not necessarily positive random variables whose negative parts have finite moment-generating functions.
