ABSTRACT

In this work, suppose that {X n ; n ≥ 1}is a sequence of asymptotically negatively associated random variables and {a ni ; 1 ≤ in, n ≥ 1} is an array of real numbers such that i=1n|ani|q=O(n) for some q > max {αp1α1/2,2} with αp > 1 and α>12 . Let l (x) > 0 be a slowly varying function at infinity. We establish some equivalent conditions of the complete convergence for weighted sums of this form

n=1nαp2l(n)P(max1jn|i=1janiXi|>εnα)<forallε>0.

As applications, some strong laws of large numbers for weighted sums of asymptotically negatively associated random variables are also obtained.
