• #### Compositional random data: a routine for CoDaPack ﻿

(CIMNE, 2011)
Conference report
Open Access
Generation of random variables are needed in the simulations of many natural process. For some random variables, di erent methodologies are known, specially into euclidean spaces. In this paper a routine for dealing with ...
• #### Log-ratio methods in mixture models for compositional data sets ﻿

Article
Open Access
When traditional methods are applied to compositional data misleading and incoherent results could be obtained. Finite mixtures of multivariate distributions are becoming increasingly important nowadays. In this paper, ...
• #### Modelling count data using the logratio-normal-multinomial distribution ﻿

Given a graph $G$=($V$,$E$), a positive integer $k$ and a positive integer $d$, we want find a subset $V_k$ with $k$ vertices such the graph obtained by identifying the vertices from $V_k$ in $G$ has diameter at most $d$. ...
