The cIRT package (CRAN, GitHub) is home to the implementation of Choice Item Response Theory (cIRT) described by Culpepper and Balamuta (2015). cIRT jointly models the accuracy of cognitive responses and item choices within a bayesian hierarchical framework.

In this update, we prepared the package for the incoming C++ function registration changes. We are making this update to ensure cIRT remains on CRAN.
