RMallow - Fit Multi-Modal Mallows' Models to Ranking Data

An EM algorithm to fit Mallows' mixture models to full or partial rankings, with or without ties. The Mallows model is a distance-based probability model over rankings, where probability decreases exponentially with distance from a central (modal) ranking. This package implements mixture models to handle multi-modal ranking data, as described in Murphy and Martin (2003) <doi:10.1016/S0167-9473(02)00165-2> and Adkins and Fligner (1998) <doi:10.1080/03610929808832223>.
