%description
Nonparametric unfolding item response theory (IRT) model for dichotomous
data (see W.H. Van Schuur (1984). Structure in Political Beliefs: A New
Model for Stochastic Unfolding with Application to European Party
Activists, and W.J.Post (1992). Nonparametric Unfolding Models: A Latent
Structure Approach). The package implements MUDFOLD (Multiple
UniDimensional unFOLDing), an iterative item selection algorithm that
constructs unfolding scales from dichotomous preferential-choice data
without explicitly assuming a parametric form of the item response
functions. Scale diagnostics from Post(1992) and estimates for the person
locations proposed by Johnson(2006) and Van Schuur(1984) are also
available. This model can be seen as the unfolding variant of Mokken(1971)
scaling method.
