Wang, Tianyou; Zeng, Lingjia
Applied Psychological Measurement, v22 n4 p333-44 Dec 1998
Develops an item-parameter estimation procedure using an EM algorithm for the continuous-response model (F. Samejima, 1973). Examines the usefulness of this model using simulated data. Results show that the procedure performs well in estimating items and theta parameters. (SLD)
