Useful Tools for Cognitive Diagnosis Modeling

Provides useful tools for cognitive diagnosis modeling (CDM). The packages includes the discrete factor loading method for Q-matrix estimation (Wang, Song, & Ding, 2018, ) and the Hull method for Q-matrix validation (Nájera, Sorrel, de la Torre, & Abad, 2021, ). It also provides dimensionality assessment procedures for determining the number of attributes underlying CDM data, including parallel analysis and automated CDM fit comparison as explored in Nájera, Abad, and Sorrel (2021, ). Lastly, the package provides some useful functions for CDM simulation studies, such as random Q-matrix generation and detection of complete/identified Q-matrices.
