| Abstract | In this study, covariates are incorporated to improve classification accuracy in large dimensional cognitive diagnostic tests. The performance of the proposed approach was examined in a simulation study. Results showed that the proposed approach could increase information obtained from CDM and improve the classification accuracy when tests are not informative. |
