rgmm: Sample a Generalized Mallows Model

Description

Generate a sample of n permutations from a Generalized Mallows Model (GMM).

Usage

rgmm(n, sigma0, theta, dist.name = "kendall",
  sampling.method = "multistage")

Arguments

n

the number of permutations to be generated

sigma0

central permuation of the GMM

theta

dispersion parameter vector of the GMM

dist.name

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

sampling.method

optional name of the sampling algorithm. One of: multistage, gibbs (default)

Value

A matrix contaning a sample of permutations from the specified ditribution
