A Unidimensional Item Response Model for Unfolding Responses from a Graded Disagree-Agree Response Scale.
Roberts, James S.; Laughlin, James E.
Applied Psychological Measurement, v20 n3 p231-55 Sep 1996
A parametric item response theory model for unfolding binary or graded responses is developed. The graded unfolding model (GUM) is a generalization of the hyperbolic cosine model for binary data of D. Andrich and G. Luo (1993). Applicability of the GUM to attitude testing is illustrated with real data. (SLD)
