The Added Value of Multidimensional IRT Models

Bayesian Irt Models Incorporating General and Specific Abilities

IRT-based models with a general ability and several specific ability dimensions are useful. Studies have looked at item response models where the general and specific ability dimensions form a hierarchical structure. It is also possible that the general and specific abilities directly underlie all test items. A multidimensional IRT model with such an additive structure is proposed under the Bay...

An Evaluation of the IRT Models Through Monte Carlo Simulation

Item response theory (IRT) models are commonly used in the realm of educational and psychological testing. The three commonly used IRT models for responses that are graded as either correct or incorrect are the One-parameter, Two-parameter, and Three parameter IRT models. These models are used to calibrate standardized tests and to assess human latent traits such as student’s overall intelligen...
