Distribution of the LR criterion Up,m,n as a marginal distribution of a generalized Dirichlet model
Statistica, 2013 The density of the likelihood ratio criterion Up,m,n is expressed in terms of a marginal density of a generalized Dirichlet model having a specific set of parameters.

A Fractional Generalization of the Dirichlet Distribution and Related Distributions [PDF]
Fractional Calculus and Applied Analysis, 2021 This paper is devoted to a fractional generalization of the Dirichlet distribution. The form of the multivariate distribution is derived assuming that the $n$ partitions of the interval $[0,W_n]$ are independent and identically distributed random variables following the generalized Mittag-Leffler distribution. The expected value and variance of the one-

A GENERALIZATION OF DIRICHLET TYPE 1 DISTRIBUTION [PDF]
International Journal of Pure and Apllied Mathematics, 2014 ABSTRACT: In this article, we give a generalization of the Dirichlet type 1 distribution. This generalization is based on the Lauricella’s type B hypergeometric function.

A generalization of the Dirichlet distribution
Journal of Multivariate Analysis, 2013 A new parametric family of distributions on the unit simplex is proposed and investigated. Such family, called flexible Dirichlet, is obtained by normalizing a correlated basis formed by a mixture of independent gamma random variables. The Dirichlet distribution is included as an inner point. The flexible Dirichlet is shown to exhibit a rich dependence

A Generalization of the Dirichlet Distribution [PDF]
Journal of Statistical Software, 2010 This paper discusses a generalization of the Dirichlet distribution, the ‘hyperdirichlet’, in which various types of incomplete observations may be incorporated. It is conjugate to the multinomial distribution when some observations are censored or grouped. The hyperdirichlet R package is introduced and examples given. A number of statistical tests are

On Joint Distribution of General Dirichlet Series
Nonlinear Analysis: Modelling and Control, 2003 In the paper a joint limit theorem in the sense of the weak convergence in the space of meromorphic functions for general Dirichlet series is proved under weaker conditions as in [1].

Acceleration and Spectral Redistribution of Cosmic Rays in Radio-jet Shear Flows
The Astrophysical Journal, 2023 A steady-state, semi-analytical model of energetic particle acceleration in radio-jet shear flows due to cosmic-ray viscosity obtained by Webb et al. is generalized to take into account more general cosmic-ray boundary spectra.

Lattice permutations and Poisson-Dirichlet distribution of cycle lengths [PDF]
, 2012 We study random spatial permutations on ℤ3 where each jump x↦π(x) is penalized by a factor e−T∥x−π(x)∥2 . The system is known to exhibit a phase transition for low enough T where macroscopic cycles appear.
