Validation of Fuzzy set Qualitative Comparative Analysis (fsQCA): Granular description of a function

Fuzzy set Qualitative Comparative Analysis (fsQCA) is a methodology for obtaining linguistic summarizations from data that are associated with cases. It contains 13 steps which are mathematically described in [2]. In this paper we focus on the validation of fsQCA by using it to obtain a granular (linguistic) description of a function as a collection of fuzzy IF-THEN rules, where the rules may be viewed as a summary of the function.
