The Q-Matrix Validation Methods Framework
Description
Provide a variety of Q-matrix validation methods for the generalized
cognitive diagnosis models, including the method based on the generalized
deterministic input, noisy, and gate model (G-DINA) by de la Torre (2011)
discrimination index (the GDI method) by
de la Torre and Chiu (2016) , the Hull method
by Najera et al. (2021) , the stepwise Wald test method
(the Wald method) by Ma and de la Torre (2020) , the
multiple logistic regression‑based Q‑matrix validation method (the MLR-B method)
by Tu et al. (2022) , the beta method based on
signal detection theory by Li and Chen (2024) and
Q-matrix validation based on relative fit index by Chen et al. (2013)
. Different research methods and iterative
procedures during Q-matrix validating are available
