Modelos de Variáveis Latentes
Abstract: Many latent variables can be seen as having a hierarchical structure and some IRT models have been proposed towards this. Motivated by the limitations of the existent literature approaches and on the importance of the theme, this work aims to propose an improved methodology in terms of both modeling and inference. From a modeling perspective, the proposed methodology allows for genuinely multidimensional items, which no past work has done, with a higher order structure for latent traits, in which all of them are in the same scale. We approach computational aspects, such as sampling jointly all latent traits and we carefully devise a MCMC algorithm to be efficient.
