Necessary Condition Analysis
Necessary Condition Analysis (NCA) is an emerging approach and data analysis technique for identifying necessary (but not sufficient) conditions in data sets. It is used in the social, medical and teachnical sciences and complements traditional regression based data analysis as well as configurational methods like Qualitative Comparative Analysis (QCA). NCA provides very relevant insights for practice. Recent methodological and substantive publications show that NCA can combine rigor and relevance. Several training options for NCA are available.
