Bounds on the norming operators for distributions in the domain of attraction of an operator-stable distribution are found. These bounds are used to establish the existence and nonexistence of moments of distributions in the domain of attraction of an operator-stable distribution. Similar results for stochastically compact sequences are obtained.

Asymptotic normality, tightness, and weak convergence of the magnitude-Winsorized sums formed from symmetric i.i.d. random variables are studied via a new approach that first derives self-normalized (“studentized”) results and then uses these to derive results for constant normalizations. An application of this method to trimmed sums is also discussed to demonstrate its more general applicability as well as to illustrate its use.

If X1, X2, X3, ...,are independent, identically distributed (i.i.d.) random variables and \(S_n = \sum\nolimits_{i = 1}^n {X_i }\) otes the nth partial sum, then limit theorems such as the law of large numbers (LLN), the central limit theorem (CLT), and the law of the iterated logarithm (LIL) all involve a strong interplay between the maximal terms of the sample.{|X 1|,...,|X n|} and the asymptotic behavior of the partial sum S n . Indeed, what is shown in the proofs of the classical formulation of each of these results is that the maximal or extreme terms of the sample are negligible in a sense required for the corresponding theorem. Furthermore, since the assumptions sufficient to prove the classical version of each of these results are also necessary, we see that extensions of these limit theorems will likely require methods that nullify or at least limit the effect of the extreme terms.

This paper investigates the related properties of center and scale for distributions and features application to asymptotic normality criteria for sums of independent random variables. Necessary and sufficient conditions are given for convergence in distribution to the standard normal for suitably centered and scaled sums of independent variables in the context of uniform asymptotic negligibility of the summands (Theorem 5.1). New here is the expression of the precise conditions and prior construction of centering and scaling constants directly in terms of the distributions of the original variables, without recourse to symmetrization, and the display of the centered, scaled sums as sums of uniformly asymptotically negligible summands without the necessity of further recentering (cf. Gnedenko and Kolmogorov (1968), Chapter 6, Theorem 2, and Hahn and Klass (1981), Theorem 2 and especially Remark 2 following Theorem 1). The resulting theorem allows a direct and informative expression of Levy’s (1937) profound realization of asymptotic normality for sums as equivalent to negligibility of the summand of maximum modulus (cf. Remark 5 and equation (5.9) here following the statement of Theorem 5.1).
