Abstract

This rejoinder responds to the commentary by Liu (Psychometrika, 2015) entitled "On the consistency of Q-matrix estimation: A commentary" on the paper "A general method of empirical Q-matrix validation" by de la Torre and Chiu (Psychometrika, 2015). It discusses and addresses three concerns raised in the commentary, namely the estimation accuracy when a provisional Q-matrix is used, the consistency of the Q-matrix estimator, and the computational efficiency of the proposed method.

Keywords: G-DINA; MMLE; Q-matrix; cognitive diagnosis; validation.
