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 step-wise Wald test method (the Wald method) by Ma and de la Torre (2020) , the Hull method by Najera et al. (2021) , the multiple logistic regression-based Q-matrix validation method (the MLR-B method) by Tu et al. (2022) . Different research methods during Q-matrix validating are available.
