Curiosities of QCA: Fuzzyset consistency
Qualitative Comparative Analysis (QCA) is the method of choice for the analysis of set relations and has changed considerably and improved over the years. The more one delves into the method, however, the more things you (I, at least) stumble … Continue reading
