On the Efficiency of IRT Models When Applied to Different Sampling Designs.
Berger, Martjin P. F.
Applied Psychological Measurement, v15 n3 p293-306 Sep 1991
A generalized variance criterion is proposed to measure efficiency in item-response-theory (IRT) models. Heuristic arguments are given to formulate the efficiency of a design in terms of an asymptotic generalized variance criterion. Efficiencies of designs for one-, two-, and three-parameter models are compared. (SLD)
