On Multidimensional Item Response Theory: A Coordinate-Free Approach. Research Report. ETS RR-07-30
Antal, Tamás
ETS Research Report Series, Jul 2007
A coordinate-free definition of complex-structure multidimensional item response theory (MIRT) for dichotomously scored items is presented. The point of view taken emphasizes the possibilities and subtleties of understanding MIRT as a multidimensional extension of the classical unidimensional item response theory models. The main theorem of the paper is that every monotonic MIRT model looks the same; they are all trivial extensions of univariate item response theory.
