Coincidence Analysis (CNA)

Coincidence Analysis (CNA) is a configurational comparative method (CCM) of causal inference and data analysis that is custom-built for multi-outcome structures.


This page presents some relevant literature on CNA and will inform about new developments, seminars, workshops etc. For more see the official CNA website at the University of Bergen.
