expectation.mm

theta

length of the permutation in the
  considered model

perm.length

optional name of the distance used in
  the MM. One of: kendall (default), cayley, hamming, ulam

dist.name

Compute the expected distance in the MM under the Hamming
distance

This package 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 in those related with the Kendall's-$\tau$, Cayley, Ulam and Hamming distances and the random generation of permutations.

expectation.mm: Compute the expected distance, MM under the Hamming distance
