EstCRM: Calibrating Parameters for the Samejima's Continuous IRT Model

The EstCRM package estimates item and person parameters for the Samejima's Continuous Response Model (CRM), computes item fit residual statistics, draws empirical 3D item category response curves, draws theoretical 3D item category response curves, and generates data under the CRM for simulation studies.
