Compositional Random Data: a Routine for CoDaPack

Abstract

Generation of random variables are needed in the simulations of many natural process. For some random variables, different methodologies are known, specially into euclidean spaces. In this paper a routine for dealing with random variables into a simplex space with the Aitchison geometry is presented. The routine has been implemented for the CoDaPack, a freeware software developed to be used for users with minimum programming skills
