Separate versus Concurrent Estimation of IRT Item Parameters in the Common Item Equating Design [electronic resource] / Bradley A. Hanson and Anton A. Beguin.

Item response theory (IRT) item parameters can be estimated using data from a common item equating design either separately for each form or concurrently across forms. This paper reports the results of a simulation study of separate versus concurrent item parameter estimation. Using simulated data f...
