  "Description": "Framework for the Item Response Theory analysis of\ndichotomous and ordinal polytomous outcomes under the\nassumption of within-item multidimensionality and discreteness\nof the latent traits. The fitting algorithms allow for missing\nresponses and for different item parametrizations and are based\non the Expectation-Maximization paradigm. Individual covariates\naffecting the class weights may be included in the new version\ntogether with possibility of constraints on all model\nparameters.",
