Abstract

Let {Xk, k => 1} be a sequence of i.i.d.r.v.s with common distribution function (d.f.) F. Suppose F belongs to the domain of normal attraction of a stable law  with index σ, 1 < σ  ≤ 2 and F satisfies some regularity conditions. Let Sn = X1 + ... + Xn  and g be a real differentiable function such that |g'(x) - g'(y)| ≤ L |x - y|, L>0. We give uniform rate of convergence in the Central Limit Theorem (CLT) for the sequence:
( (n^1-r) / g'(o) ) { g(sn / n) - g(0) },  n ≥ 1, g'(0) ≠ 0
