Hierarchical irt
WebFive factors are manipulated with higher-order IRT models and hierarchical IRT models: (1) the different correlation conditions between two primary factors (low, medium, and high), (2) the number of group factors per primary factor (two and four), (3) the number of items (40, 80 and 160), (4) the item selection method (MFI and Bayesian), and (5) the proficiency … WebhIRT is an R package that implements a class of hierarchical item response theory (IRT) models where both the mean and the variance of the latent “ability parameters” may …

Web9 de nov. de 2007 · Recently, attention has been paid to IRT-based models with an overall ability dimension underlying several ability dimensions specific for individual test items, where the focus is mainly on models with dichotomous latent traits. The purpose of this study is to propose such models with continuous latent traits under the Bayesian … WebThe hierarchical item response theory (H-IRT) model is very flexible and allows a general factor and subfactors within an overall structure of two or more levels. When an H-IRT model with a large number of dimensions is used for an adaptive test, the computational burden associated with interim scoring and selection of subsequent items is heavy.
