摘要：

It is pointed out that the q-exponential distribution introduced in the ground-breaking paper by Tsallis [C. Tsallis, J. Stat. Phys. 52 (1988) 479] is contained by a family of distributions known since the 1940s. Some elementary statistical properties of this family are discussed. Six data sets on fracture roughness are used to demonstrate that this family provides much better models for fracture roughness than the q exponential distribution. (c) 2006 Elsevier B.V.
