Calibrating Parameters for the Samejima’s Continuous Response Model
EstCRM is an R package develope to calibrate the item and person parameters from the Samejima’s Continuous Response Model for continous measurement outcomes. It estimates item and person parameters for the Samejima’s Continuous Response Model, 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.
