ABSTRACT
Statistical models on full and partial rankings of n items are often of
limited practical use for large n due to computational consideration. We
explore the use of non-parametric modeling and visualization for
partially ranked data and derive computationally efficient procedures
for their use for large n. The derivations are largely possible through
combinatorial and algebraic manipulations based on the lattice of
partial rankings. A bias-variance analysis and an experimental study
demonstrate the applicability of the proposed method.
