CopyDetect: An R Package for Computing Statistical Indices to Detect Answer Copying on Multiple-Choice Tests

This R package contains several IRT and non-IRT based statistical indices proposed in the literature for detecting answer copying on multiple-choice examinations. The current R package includes the indices that have been shown as effective and reliable based on the simulation studies. The CopyDetect package provides results for the Omega index (Wollack, 1996), Generalized Binomial Test (van der Linden & Sotaridona, 2006), K index (Holland, 1996), K1 and K2 indices (Sotaridona & Meijer, 2002), and S1 and S2 indices (Sotaridona & Meijer, 2003).
