This methodology stands between the qualitative and the quantitative methods and helps researchers to build middle-range theories (Mjoset, 2001) from small to intermediate numbers of cases. This methodology encompasses a number of techniques including crisp and fuzzy set-theoretic qualitative comparative ...

As stressed in [1] and [12] an interesting question on philosophy of probability is to assign probabilistic valuations to individual phenomenon. In [10] such a question was discussed and a solution was proposed. In this chapter we start from the ideas in
a fuzzy set in U , and A ~ µ is the membership function for any U x i ! whose output is located between 0 and 1, representing the membership degree. Equations (2) and (3) represent the membership degrees of a fuzzy set and crisp set, respectively. ! ! ! " ! ! !

Section 2 of this paper provides a brief introduction to the fuzzy-set approach, building on Ragin (2000). Fuzzy sets are especially powerful because they allow researchers to calibrate partial membership in sets using values in the interval between 0 (nonmembership) and 1 (full membership) ...
