Researchers working with Qualitative Comparative Analysis (QCA)
can use the package to estimate power of a sufficient term
using permutation tests. A term can be anything: A condition, conjunction or
disjunction of any combination of these. The package further allows users to plot
the estimation results and to estimate the number of cases required to achieve a
certain level of power, given a prespecified null and alternative hypothesis.
