Statistics of Fuzzy Data: A Research Direction for Applied Statistics

Abstract

We emphasize problems where fuzzy data appear naturally and need to be used and analyzed properly within the context of applied statistics. To enlarge the practice of statistics to this new types of observed data, we need to place fuzzy data within the context of probability theory. Having a theory of statistics of fuzzy data, applied statisticians can embark on a promising road of important applications, especially in economics, whereas otherwise these problems are either ignored or badly handled.
