decisionfacets: Decision Accuracy and Consistency for Rater-Mediated Exams

Answers "would this candidate have passed with a different set of raters?" for rater-mediated exams such as oral examinations, objective structured clinical examinations and essay scoring. Builds on the many-facet extension of the rating scale model (Andrich, 1978, <doi:10.1007/BF02293814>) to compute counterfactual pass probabilities under the observed, an average-severity and a random rater panel, under an explicit decision rule (raw total, fair average or measure), and splits expected misclassification into measurement error and rater assignment, extending item response theory classification accuracy (Lee, 2010, <doi:10.1111/j.1745-3984.2009.00096.x>) to rater effects. Models can be fitted with 'TAM' or a built-in joint maximum likelihood estimator.
