Abstract

Latent attributes in cognitive diagnostic models (CDMs) are dichotomous, but in practice polytomous attributes are possible. We developed a set of new CDMs in which the polytomous attributes are assumed to measure the same continuous latent trait. Simulation studies demonstrated good parameter recovery using WinBUGS. An empirical example was given.
