New NCA software release with statistical test

Version 3.0 of the NCA software has become available. This version contains a statistical significance test for NCA. An article about the test was just accepted in the journal Organizational Research Methods. The test estimates the p-value of a calculated necessity effect size. A low p-value (e.g., p < 0.05), helps NCA researchers to prevent drawing false positive conclusions about the observed effect. The article and a Quick Start Guide of the software can be found on the NCA website: www.erim.nl/nca. Existing users of the NCA software can update their NCA package by using update.packages("NCA").
