The package includes functions for estimating CDMs such\nas the restricted DINA or DINO (R-DINA or R-DINO) models\n(Nájera et al., 2023; ), the\nG-DINA model for forced-choice blocks (Nájera et al., 2024;\n), and the general nonparametric\nclassification method (Chiu et al., 2018;\n). Additionally, methods for\nidentifying the latent structure of CDMs are also available,\nsuch as dimensionality assessment via parallel analysis and\nautomated fit comparison (Nájera et al., 2021;\n), as well as empirical Q-matrix\nvalidation and estimation using the Hull method (Nájera et al.,\n2021; ) and the discrete factor loading\nmethod (Wang et al., 2018; ).\nOther practical functions for CDM applications include\ncorrected classification accuracy estimation via multiple\nimputation (Kreitchmann et al., 2022;\n), model-based recursive\npartitioning to detect non-invariant subpopulations (Nájera et\nal., in press), person-fit evaluation (Santos et al., 2020;\n), and model identifiability\nassessment (Gu and Xu, 2021; ).\nLastly, the package also provides useful functions for CDM\nsimulation studies, such as random Q-matrix generation and\nforced-choice data generation.", "License": "GPL-3", "URL": "https://github.com/pablo-najera/cdmTools", "BugReports": "https://github.com/pablo-najera/cdmTools/issues", "Encoding": "UTF-8", "Author": "Pablo Nájera [aut, cre, cph], Miguel A.
