Abstract

Let F be a distribution function with all moments finite and such that the problem of moments for F has a nonunique solution (F is M-indeterminate). Our goal is to explicitly describe a Stieltjes class S = {f ε = f[1 + εh], ε ∈ [-1, 1]} of distributions (here written in terms of the densities) all having the same moments as F. We study in detail the case when F is the distribution of the power transformation ξr, r > 0 of a random variable ξ with generalized gamma distribution. We derive new Stieltjes classes in this case and also for powers of the normal and the exponential distributions. We find the value of the index of dissimilarity for some of these classes. © Elsevier B.V. All rights reserved.
