“…The article by Sorrel, Escudero, Nájera, Kreitchmann, and Vázquez-Lira [9], titled "Exploring approaches for estimating parameters in cognitive diagnosis models with small sample sizes", compares different estimation methods for cognitive diagnostic models (CDM, also referred to as diagnostic classification models (DCM)) in small samples. The study found that alternative estimation methods should be preferred over the usually employed marginal maximum likelihood (MML) estimation approach when estimating CDMs in small samples.…”
