MLCIRTwithin (version 1.0)
Latent Class Item Response Theory Models Under 'Within-Item
Multi-Dimensionality'
Description
Framework for the Item Response Theory analysis of dichotomous and ordinal polytomous outcomes under the assumption of within-item multi-dimensionality and discreteness of the latent traits. The fitting algorithms allow for missing responses and for different item parameterizations and are based on the Expectation-Maximization paradigm. Individual covariates affecting the class weights may be included in the new version.
