Using LASSO regularization to evaluate measurement bias in a 2-parameter logistic IRT model. | More modeling possibilities with regDIF.
Package: regDIF 1.1.0
regDIF: Regularized Differential Item Functioning
Performs regularization of differential item functioning (DIF) parameters in item response theory (IRT) models (Belzak & Bauer, 2020) <https://pubmed.ncbi.nlm.nih.gov/31916799/> using a penalized expectation-maximization algorithm.
