Tests statistiques sur les distributions de Dirichlet. (French) Zbl 0575.62023

Dirichlet’s distribution and its associated statistical family are defined on unit simplex of the Euclidean space \(R^ M\) (M\(\geq 2)\). They depend on M positive scalar parameters \(a_ i\). We examine statistical tests (one and two sided) about one particular \(a_ i\), the others being known or not (nuisance parameters). We study also another parametrization.
