Subject: QCA version 0.4-5
QCA implements the Qualitative Comparative Analysis using a boolean
minimization algorithm for data coded with presence/absence of the causal
conditions that affects a phenomenon of interest.
This new release has an experimental function that obtains the same exact
solutions as the main minimization function, using a shortcut instead of the
classical complete and exhaustive algorithm. This new function is faster and
uses significantly less memory (50 MB compared to 1.5 GB for large datasets).
It should appear soon on CRAN, feedback is welcome.
