The estimation of item response models with the lmer function from the lme4 package in R
Paul De Boeck,Marjan Bakker,Robert J. Zwitser,Michel G. Nivard,Abe D. Hofman,Francis Tuerlinckx,Ivailo Partchev +6 more
TL;DR: In this article, the potential of the lmer function from the lme4 package in R for item response (IRT) modeling is discussed, and three broad categories of models are described: item covariate models, person covariate model, and person-by-item model.
Journal ArticleDOI
A nonlinear mixed model framework for item response theory.
TL;DR: It is shown how a variety of IRT models can be formulated as particular instances of nonlinear mixed models, and the unifying framework offers the advantage that relations between different I RT models become explicit and that it is rather straightforward to see how existing IRT Models can be adapted and extended.
Journal ArticleDOI
Hierarchical classes: Model and data analysis
Paul De Boeck,Seymour Rosenberg +1 more
TL;DR: A discrete, categorical model and a corresponding data-analysis method are presented for two-way two-mode data arrays with 0, 1 entries that aims at recovering the underlying structure in a data matrix by minimizing the discrepancies between the data and the recovered structure.
Journal ArticleDOI
Random Item IRT Models.
TL;DR: It is shown in the present article that random item parameters make sense theoretically, and that in practice the random item approach is promising to handle several issues, such as the measurement of persons, the explanation of item difficulties, and trouble shooting with respect to DIF.
