Parameter Recovery for the Rating Scale Model Using PARSCALE.
French, Guy A.; Dodd, Barbara G.
Journal of Outcome Measurement, v3 n2 p176-99 1999
Studied item and trait parameter recovery for Andrich's rating-scale model (D. Andrich, 1978) using the PARSCALE computer program. Simulation results suggest that Andrich's rating scale allows the use of considerably smaller calibration samples than are typically recommended for other polytomous item-response-theory models.
