    QCA-Workshop in Saarbrücken

    Am 12./13. Oktober habe ich an der Universität des Saarlandes in Saarbrücken einen QCA-Workshop für das CEUS-Nachwuchskolleg am Cluster für Europaforschung gehalten. In dem kompakten zweitägigen Format wurden die Grundlagen von QCA auf Basis von Qualitative Comparative Analysis: An Introduction to Research Design and Application erörtert, Anwendungsbeispiele besprochen und die Anwendung der Software anhand des kürzlich aktualisierten R Manual for QCA vorgestellt. Herzlichen Dank an Prof. Dr. Georg Wenzelburger und das Team der Professur für Politikwissenschaft mit Schwerpunkt komparative Europaforschung sowie an Dr. Florian Rossbach, Koordinator des Nachwuchskollegs Europa, für die Einladung nach Saarbrücken und an alle Teilnehmenden für den konstruktiven Workshop!

    R Manual for QCA, version 3.0

    The R Manual for QCA has been updated to version 3.0. Among other changes and updates, the current version includes further guidance on forming different types of intermediate solutions and on visualizing QCA results, particularly on how to create suitable XY plots and how to customize them in line with one’s own research aims. The R Manual for QCA (PDF file, R Script, and sample data) can be downloaded on this website and on Harvard Dataverse: https://doi.org/10.7910/DVN/KYF7VJ.

    The R Manual for QCA is freely available as an online appendix to Qualitative Comparative Analysis: An Introduction to Research Design and Application (Georgetown University Press, 2021).
