MLCIRTwithin (2.1.1)

Latent Class Item Response Theory (LC-IRT) Models under Within-Item Multidimensionality.

http://cran.r-project.org/web/packages/MLCIRTwithin

Framework for the Item Response Theory analysis of dichotomous and ordinal polytomous outcomes under the assumption of within-item multidimensionality and discreteness of the latent traits. The fitting algorithms allow for missing responses and for different item parametrizations and are based on the Expectation-Maximization paradigm. Individual covariates affecting the class weights may be included in the new version together with possibility of constraints on all model parameters.
