Package: MLCIRTwithin Type: Package Title: Latent Class Item Response Theory (LC-IRT) Models under Within-Item Multidimensionality Version: 2.1.2 Date: 2025-06-27 Authors@R: c(person(given = "Francesco", family = "Bartolucci", role = c("aut", "cre"), email = "francesco.bartolucci@unipg.it"), person(given = "Silvia", family = "Bacci", role = "aut")) Author: Francesco Bartolucci [aut, cre], Silvia Bacci [aut] Maintainer: Francesco Bartolucci Description: 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.
