A Generalized Partial Credit Model: Application of an EM Algorithm.
Muraki, Eiji
Applied Psychological Measurement, v16 n2 p159-76 Jun 1992

Analysis results for simulated data by this and other polytomous item-response models demonstrate that the rating formulation of the GPCM is adaptable to the analysis of polytomous item responses.
