Analysis of dichotomous and polytomous response data using the explanatory item response modeling framework, as described in Bulut, Gorgun, & Yildirim-Erbasli (2021) doi:10.3390/psych3030023, Stanke & Bulut (2019) doi:10.21449/ijate.515085, and De Boeck & Wilson (2004) doi:10.1007/978-1-4757-3990-9. Generalized linear mixed modeling is used for estimating the effects of item-related and person-related variables on dichotomous and polytomous item responses.
