The Dirichlet distribution with respect to the Aitchison measure on the simplex - a first approach

http://dugi.udg.edu/item/http:@@@@hdl.handle.net@@2072@@14684

The algebraic-geometric structure of the simplex, known as Aitchison geometry, is usedto look at the Dirichlet family of distributions from a new perspective. A classicalDirichlet density function is expressed with respect to the Lebesgue measure on realspace. We propose here to change this measure by the Aitchison measure on thesimplex, and study some properties and characteristic measures of the resulting density
