A Hyperbolic Cosine Latent Trait Model for Unfolding Dichotomous Single-Stimulus Responses.

Andrich, David; Luo, Guanzhong

Applied Psychological Measurement, v17 n3 p253-76 Sep 1993

A unidimensional model for responses to statements that have an unfolding structure was constructed from the cumulative Rasch model for ordered response categories. A joint maximum likelihood estimation procedure was investigated. Analyses of data from a small simulation and a real data set show that the model is readily applicable. (SLD)
