  "Description": "Framework for the Item Response Theory analysis of\ndichotomous and ordinal polytomous outcomes under the\nassumption of multidimensionality and discreteness of the\nlatent traits. The fitting algorithms allow for missing\nresponses and for different item parameterizations and are\nbased on the Expectation-Maximization paradigm. Individual\ncovariates affecting the class weights may be included in the\nnew version (since 2.1).",
