Limits on Log Cross-Product Ratios for Item Response Models. Research Report. ETS RR-06-10
Haberman, Shelby J.; Holland, Paul W.; Sinharay, Sandip
ETS Research Report Series, May 2006
Bounds are established for log cross-product ratios (log odds ratios) involving pairs of items for item response models. First, expressions for bounds on log cross-product ratios are provided for unidimensional item response models in general. Then, explicit bounds are obtained for the Rasch model and the two-parameter logistic (2PL) model. Results are also illustrated through an example from a study of model-checking procedures. The bounds obtained can provide a basis for assessment of goodness of fit of these models.
