Structure in\nPolitical Beliefs: A New Model for Stochastic Unfolding with\nApplication to European Party Activists, and W.J.Post (1992).\nNonparametric Unfolding Models: A Latent Structure Approach).\nThe package implements MUDFOLD (Multiple UniDimensional\nunFOLDing), an iterative item selection algorithm that\nconstructs unfolding scales from dichotomous\npreferential-choice data without explicitly assuming a\nparametric form of the item response functions. Scale\ndiagnostics from Post(1992) and estimates for the person\nlocations proposed by Johnson(2006) and Van Schuur(1984) are\nalso available.
