count.perms.cycles

perm.length

number of cycles of the permutations to count

num.cycles

Given the number of items in the permutations,
how many permutations are there with with the given number of cycles?

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.
