Bayesian Estimation of MIRT Models with General and Specific Latent Traits in MATLAB
Multidimensional item response models have been developed to incorporate a general trait and several specific trait dimensions. Depending on the structure of these latent traits, different models can be considered. This paper provides the requisite information and description of software that implement the Gibbs sampling procedures for three such models with a normal ogive form. The software de...

15 صفحه اولBayesian 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...
متن کاملSemiparametric Bayesian latent trajectory models
Latent trajectory models (LTMs) characterize longitudinal data using a finite mixture of curves. We address uncertainty in the number of latent classes and in the form of the class-specific curves using a semiparametric Bayesian approach. A mixture of functional Dirichlet processes (FDP) is used to characterize the distribution of longitudinal trajectories. The FDP is defined by replacing the a...
