QCA-package {QCA} | R Documentation |
This library implements the comparative methodology as described in Ragin (1987) and Ragin (2000). The analysis is the bridge between the qualitative and quantitative worlds, making use of the qualitative procedures in a systematic, algorithmic way (therefore increasing the "confidence" in the results, as understood by quantitative researchers). At this first release, only the ''exact'' Quine-McCluskey algorithm for crisp sets is implemented. However it is widely known that, for large number of conditions (over 10), the algorithm is memory hungry therefore very slow. The next versions will have more functions to address this problem, as well as functions for fuzzy-set QCA. The package doesn't currently handle missing values in the data, therefore it is not yet possible to perform simplifying assumptions
