Abstract:
Qualitative comparative analysis (QCA) is an increasingly popular analytic strategy, with applications to numerous empirical fields. This article briefly discusses the substantive motivation and technical details of QCA, as well as fuzzy-set QCA, followed by an in-depth discussion of how the new program fuzzy performs these techniques in Stata. An empirical example is presented that demonstrates the full suite of tools contained within fuzzy, including creating configurations, performing a series of statistical tests of the configurations, and reducing the identified configurations.
