  1. Set-valued Data

    Since fuzzy sets are generalizations of ordinary sets, we present in this Chapter the essentials of random set theory for statistics. This material...

    Chapter
  4. Tests of Hypothesis: Means

    In many expositions of fuzzy methods, fuzzy techniques are described as an alternative to a more traditional statistical approach. In this chapter,...

  7. Random Fuzzy Sets

    Statistical models for observations which are numbers or vectors are random variables and random vectors, respectively. Similarly, if the...

  9. Introduction

    First like fuzzy logics are logics with fuzzy concepts, by fuzzy statistics we mean statistics with fuzzy data. Data are fuzzy when they are...
