Separability of Item and Person Parameters in Response Time Models.
Van Breukelen, Gerard J. P.
Psychometrika, v62 n4 p525-44 Dec 1997
Discusses two forms of separability of item and person parameters in the context of response time models. The first is "separate sufficiency," and the second is "ranking independence." For each form a theorem stating sufficient conditions is proved. The two forms are shown to include several cases of models from psychometric and biometric literature. (SLD)
