Ellis, Jules L.; van den Wollenberg, Arnold L.
Psychometrika, v58 n3 p417-29 Sep 1993
Characterizations of local homogeneity and the homogeneous monotone item response theory (IRT) model are provided. The characterization theorem states that the joint condition of experimental independence and pairwise nonnegative association in every nonnegligible subpopulation is necessary and sufficient for the homogenous monotone IRT model.
