A latent class scaling approach is presented for
modeling paired comparison and "pick-any/t"
data obtained in a preference study. Although the
latent class part of the model identifies homogeneous
subgroups that are characterized by their
choice probabilities for a set of alternatives, the
scaling part of the model describes the single peakedness
structure of the choice data. Procedures
are suggested for examining the unfolding structure
in an unrestricted latent class solution. Two
applications are presented to illustrate the technique.
In the first application, scaling solutions obtained
from a latent class scaling model and a marginal
maximum likelihood latent trait model are compared.

comparison data, pick any/t data, unfolding models.
