Common Item Equating Using the Loglinear Rasch Model.

Kelderman, Henk

Journal of Educational Statistics, v13 n4 p319-36 Win 1988

A method is proposed for equating different sets of items administered to different groups using the Rasch model. The Rasch equating model formulated describes one common Rasch scale in different groups with different but overlapping item sets. The model, based on the quasi-loglinear Rasch model, can be tested globally. (SLD)
