NPCD: Nonparametric Methods for Cognitive Diagnosis
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.
