摘要：

A bound on the absolute difference between two distributions, based on entropy, is introduced. Such a bound can be made as precise as desired, according to the number of common fractional moments assumed. The approximating distribution is obtained by maximizing the entropy constrained by fractional moments. (C) 2002 Elsevier Inc. All rights reserved.
