Package: qcapower Type: Package Title: Estimate Power and Required Sample Size in QCA Version: 0.2.0 Imports: ggplot2, ggforce, stats Authors@R: c( person("Ingo", "Rohlfing", email = "ingo.rohlfing@uni-passau.de", role = c("aut", "cre"), comment = c(ORCID = "0000-0001-8715-4771")), person("Holger", "Doering", email = "doering@uni-bremen.de", role = c("aut"), comment = c(ORCID = "0000-0002-6616-8805")), person("Ayjeren", "Rozyjumayeva", role = c("aut"))) Depends: R (>= 2.10) Description: 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.
