Evaluating equating results in the non-equivalent groups with anchor test design using equipercentile and equity criteria

"In this study, the performance of four commonly used equating methods under the nonequivalent group with anchor test (NEAT) design - the frequency estimation equipercentile method (FE), the chain equipercentile method (CE), the item response theory (IRT) true score method (TS), and the IRT observed score method (OS) - were examined"--From abstract.
