naep

This dataset contains the responses of a sample of 1510 examinees to 12 binary items on Mathematics. It has been
extrapolated from a larger dataset collected in 1996 by the Educational Testing Service within the National Assessment of 
Educational Progress (NAEP) project.

Framework for the Item Response Theory analysis of dichotomous and ordinal polytomous outcomes under the assumption of multidimensionality 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 (since 2.1).
