An extensive set of functions to perform Qualitative Comparative Analysis: crisp sets (csQCA), temporal (tQCA), multivalue (mvQCA) and fuzzy sets (fsQCA), using a GUI - graphical user interface. QCA is a methodology that bridges the qualitative and quantitative divide in social science research. It uses a Boolean algorithm that results in a minimal causal combination which explains a given phenomenon.
The package QCA is licensed under the GPLv3, with additional licences for external libraries (see files in the inst directory for additional details)
