Simulate IRT-Based Computerized Adaptive Tests R package catIrt version 0.5.1 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 given various item selection methods, ability estimation methods, and termination criteria.
