MLCIRTwithin-package: Latent Class (LC) Item Response Theory (IRT) Models Under 'Within-Item Multi-Dimensionality'
Description
This package provides a flexible framework for the Item Response Theory (IRT) analysis
of dichotomous and ordinal polytomous outcomes
under the assumption of within-item multi-dimensionality and discreteness of latent traits (abilities).
Every level of the abilities identify a latent class of subjects. The fitting
algorithms are based on the Expectation-Maximization (EM) paradigm and
allow for missing responses and for different item parameterizations. The package also allows for the inclusion
individual covariates affecting the class weights.Details
