During the week of August 21-25, I returned to Lugano to teach the QCA workshop at the 27th Summer School in Social Science Methods at the Università della Svizzera italiana (USI). Since 2016, I have been teaching this workshop at USI. The intensive course covers the foundations and advanced uses of QCA and its application in R, based on my book Qualitative Comparative Analysis: An Introduction to Research Design and Application (Georgetown University Press, 2021) and the accompanying R Manual (R Script and PDF freely available here). Workshop sessions are split into lectures and exercises, with dedicated time for individual consultation and feedback (see also the course description on the USI website). For impressions from previous years, see here. Thanks to the team at USI for the smooth organization and to all participants for the constructive sessions!
