GRShiny-package {GRShiny}

Full information maximum likelihood estimation of IRT models.

Description

Graded response models with different estimators

Details

Analysis of polytomous response data using unidimensional and multidimensional latent trait models under the Structure Equation Modeling paradigm. Confirmatory graded response models can be estimated with ML and WLS estimators. GRM data can be simulated and analyzed. Finally, an interactive Shiny application for running a GRM analysis is supported.l
