  "Description": "Fits explanatory generalized partial credit models and\nrelated ordinal item response models with global and\nitem-specific covariate effects. Penalized marginal maximum\nlikelihood estimation is used for variable selection, detection\nof differential item functioning, and clustering of\nitem-specific covariate effects by fusion penalties. The\npackage extends the regularization approach for differential\nitem functioning in generalized partial credit models proposed\nby Schauberger and Mair (2020)\n<doi:10.3758/s13428-019-01224-2>.",
