Garner, Mary; Engelhard, George, Jr.
Journal of Applied Measurement, v3 n2 p107-28 2002
Describes a technique for obtaining item parameters of the Rasch model, a technique in which the item parameters are extracted from the eigenvectors of a matrix derived from comparisons between pairs of items. Describes advantages of this technique, which can be applied to both dichotomous and polytomous data. (SLD)
