See John Aitchison, 2003, Compositional Data Analysis. -dirifit- implements the Dirichlet model, which is highly restrictive. Otherwise you need to transform the proportions and use a multivariate multiple regression type approach.  

Nick Cox has some nice plots from the CDA tradition implemented in Stata, eg., -triplot-.

Subject: st: The dependent variable is a multi-proportion in actual values

Hello Stata experts,
 
Would anyone know of a technique to use when I want to do a regression on a dependent variable which is a multi-proportion?
 
In particular, I want to estimate the effect of gender on (1) spending on food (2) spending on clothing and (3) spending on recreation. 
 
I cannot use mlogit, because these are actual spending proportions, not categorical values, and I want to estimate them in one regression to know their relationships, like one spending increasing more than the others.  
 
Much appreciated for any help.
 
Tim
