catIrt: An R Package for Simulating IRT-Based Computerized Adaptive
Tests
Functions designed to simulate data that conform to basic
unidimensional IRT models (for now 3-parameter binary response
models and graded response models) along with Post-Hoc CAT
simulations of those models with various item selection
methods, ability estimation methods, and termination criteria.
