Description: This package performs an array of nonparametric estimation methods for cognitive diagnostic models, including nonparametric estimation of examinee attribute profiles, joint maximum likelihood estimation of examinee attribute profiles and item parameters, and nonparametric refinement of the Q-matrix, as well as parametric algorithms such as maximum likelihood estimation of examinee attribute profiles given item parameters and maximum likelihood estimation of item parameters given examinee attribute profiles.
