Calibrating Parameters for the Samejima's Continuous IRT Model CRAN Task View: Psychometrics (http://CRAN.R-project.org/view=Psychometrics) This package contains functions to estimate item and person parameters for the Samejima's Continuous Response Model (CRM), to compute item fit residual statistics, to draw empirical 3D item category response curves, to draw theoretical 3D item category response curves, and to generate data under the CRM for simulation studies.
