measr is an R package funded by the Institute of Education Sciences for estimating diagnostic classification models (also called cognitive diagnostic models) with Stan. Diagnostic classification models are confirmatory latent class models, as described by Rupp et al. (2010), Bradshaw (2016), and de la Torre and Sorrel (2023). measr automatically generates the Stan code necessary for a variety of diagnostic models, estimates the model, and provides functionality to evaluate the model’s performance using model fit indices, information criteria, and reliability metrics.
