Abstract
This paper addresses the analysis of fuzzy data from a possibilistic p erspective. The concept of a double fuzzy variable is introduced and r elated notions are defined and investigated. The properties and fuzzy parameter estimation of the possibility distribution are also investig ated. A maximum possibility likelihood principle is provided to estima te unknown fuzzy parameters. A normal possibility distribution is used as an example and estimates of its fuzzy parameters are given. The pr oposed possibility theory of fuzzy data constitutes a new approach to analyzing fuzzy data from a possibilistic point of view. (C) 1998 Else vier Science B.V.
