CopyDetect: Computing Statistical Indices to Detect Answer Copying on Multiple-Choice Tests

Contains several IRT and non-IRT based statistical indices proposed in the literature for detecting answer copying on multiple-choice examinations. Includes the indices that have been shown as effective and reliable based on the simulation studies. Provides results for the Omega index, Generalized Binomial Test, K index, K1 and K2 indices, and S1 and S2 indices.
