A Note on "Constant Latent Odds-Ratios Models and the Mantel-Haenszel Null Hypothesis" Hessen, 2005.
In a recent paper, Hessen (Psychometrika 70(3):497-516, 2005) introduces the class of constant latent odds-ratios models as an extension of the Rasch model for which the sum score is still the sufficient statistic for ability. In this paper the relation between both the general and the general parametric constant latent odds-ratios model and the Rasch model is considered.
