ON THE LINEAR COMBINATION OF THE INVERTED DIRICHLET COMPONENTS
The aim of the present paper is to extend results of Gupta and Nadarajah [4] by giving the exact distribution and the corresponding moment function of the linear combination where and has the inverted Dirichlet distribution with positive parameters and In addition, we treat the particular case where Here, we give approximation for this distribution and discuss its robustness.
