Description: Provides useful tools for cognitive diagnosis modeling (CDM). The packages includes the discrete factor loading method for Q-matrix estimation (Wang, Song, & Ding, 2018, <doi:10.1007/978-3-319-77249-3_29>) and the Hull method for Q-matrix validation (Nájera, Sorrel, de la Torre, & Abad, 2021, <doi:10.1111/bmsp.12228>). 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, <doi:10.3389/fpsyg.2021.614470>). Lastly, the package provides some useful functions for CDM simulation studies, such as random Q-matrix generation and detection of complete/identified Q-matrices.
