tropical.Gaussian {TML}

Tropical Gaussian sampling about a center of mass

Description

This function is a Gaussian-like HAR sampler about a center of mass denoted by a location parameter with scale parameter in terms of the tropical distance

Usage

tropical.gaussian(D_s, x0, I = 1, M, S)

Arguments

D_s

matrix of vertices of a tropical simplex; each row is a vertex

x0

initial point for sampler, numeric vector

I

number of states in Markov chain

M

location parameter; numeric vector indicating centroid

S

scale parameter; in terms of tropical distance

Value

next sampled point from the tropical polytope
