New article published in Journal of Open Source Software
New article on CORA and LOGIGRAM software published in the Journal of Open Source Software: Combinational Regularity Analysis (CORA) is a new member of the family of configurational comparative methods (CCMs). CORA generalizes the capabilities of existing CCMs. By means of Boolean optimization algorithms for multi-output data imported from electrical engineering, CORA can infer INUS structures…

New article published in Nature Reviews Methods Primers
New article „Logic diagrams: a visual tool with untapped potential“ published in Nature Reviews Methods Primers: Logic diagrams were originally developed at the crossroads of analytical philosophy and electrical engineering as visual representations of Boolean-algebraic functions, primarily those describing switching circuits. However, their utility and applicability extend far beyond the technical sciences. Here, we argue…

New article published in BMC Medical Research Methodology
New article „Combinational Regularity Analysis (CORA) — a new method for uncovering complex causation in medical and health research“ published in BMC Medical Research Methodology: Modern configurational comparative methods (CCMs) of causal inference, such as Qualitative Comparative Analysis (QCA) and Coincidence Analysis (CNA), have started to make inroads into medical and health research. However, these…

New book chapter on QCA published in Handbook of Research Methods in International Relations
New book chapter on QCA published in Handbook of Research Methods in International Relations: This chapter is to convince you that QCA and closely related methods of configurational data analysis can add significantly to our knowledge about cause-effect relations. A second goal is to demonstrate the workings of QCA. A third and last goal is to…

New article on QCA solution types published in Sociological Methods & Research
New article „Beyond the Facts: Limited Empirical Diversity and Causal Inference in Qualitative Comparative Analysis“ published in Sociological Methods & Research: Recent research has found the conservative (QCA-CS) and the intermediate solution type (QCA-IS) of QCA to fail fundamental tests of correctness. This problem does not affect the parsimonious solution type (QCA-PS). These findings conflict…
