Supplementary Item Response Theory Models

CRAN Package

Supplementary functions for item response models aiming to complement existing R packages. The functionality includes among others multidimensional compensatory and noncompensatory IRT models (Reckase, 2009, doi:10.1007/978-0-387-89976-3), MCMC for hierarchical IRT models and testlet models (Fox, 2010, doi:10.1007/978-1-4419-0742-4), NOHARM (McDonald, 1982, doi:10.1177/014662168200600402), Rasch copula model (Braeken, 2011, doi:10.1007/s11336-010-9190-4; Schroeders, Robitzsch & Schipolowski, 2014, doi:10.1111/jedm.12054), faceted and hierarchical rater models (DeCarlo, Kim & Johnson, 2011, doi:10.1111/j.1745-3984.2011.00143.x), ordinal IRT model (ISOP; Scheiblechner, 1995, doi:10.1007/BF02301417), DETECT statistic (Stout, Habing, Douglas & Kim, 1996, doi:10.1177/014662169602000403), local structural equation modeling (LSEM; Hildebrandt, Luedtke, Robitzsch, Sommer & Wilhelm, 2016, doi:10.1080/00273171.2016.1142856).
