Conditions for Rasch-Dichotomizability of the Unidimensional Polytomous Rasch Model.

Roskam, Edward E.; Jansen, Paul G. W.

Psychometrika, v54 n2 p317-32 Jun 1989

A general dichotomous condition is derived for the unidimensional polytomous Rasch model. The robustness of the dichotomous analysis is investigated in a simulation study. The model shows a close relation with the two-parameter Birnbaum model. (TJH)
