count.perms.unfixed.points.gtet

perm.length

unfixed

Given the number of items in the permutations and the number of unfixed points u,
how many permutations are there with at least u unfixed points?

Includes functions to work with the Mallows, Generalized Mallows and Weighted Mallows Models. The considered distances are Kendall's-tau, Cayley, Hamming and Ulam and it includes functions for making inference, sampling and learning such distributions, some of which are novel in the literature. As a by-product, PerMallows also includes operations for permutations, paying special attention to those related with the Kendall's-tau, Cayley, Ulam and Hamming distances and the random generation of permutations.
