The edina
package provides a high-performance implementation of the Exploratory Deterministic Input, Noisy ‘and’ Gate Model (EDINA) described by Chen et al. (2018). Exploratory models estimate the Q-matrix alongside other parameters within a cognitive diagnostic model (CDM) unlike confirmatory models, which require a pre-specified expert Q matrix.
