Jürgen Rost's "hierarchy of generalized Rasch models" from "The growing family of Rasch models" (Chapter 2 in "Essays on Item Response Theory", A. Boomsma et al. (Eds.), New York: Springer. 2000). "Ordinal RM" includes dichotomous, rating scale, and partial credit models. "Linear logistic RM" includes many-facet models. The SALTUS model is a "mixed LLTM" model. "Multidimensional RM" would include Georg Rasch's own "generalization to the case of more responses than one" in "An Individual-Centered Approach to Item Analysis with Two Categories of Answers" (1964). |
