%description
Main properties and regression procedures using a generalization of the
Dirichlet distribution called Simplicial Generalized Beta distribution. It
is a new distribution on the simplex (i.e. on the space of compositions or
positive vectors with sum of components equal to 1). The Dirichlet
distribution can be constructed from a random vector of independent Gamma
variables divided by their sum. The SGB follows the same construction with
generalized Gamma instead of Gamma variables. The Dirichlet exponents are
supplemented by an overall shape parameter and a vector of scales. The
scale vector is itself a composition and can be modeled with auxiliary
variables through a log-ratio transformation. Graf, M. (2017, ISBN:
978-84-947240-0-8). See also the vignette enclosed in the package.
