A New Class of Non-Central Dirichlet Distributions

In the present paper new light is shed on the non-central extensions of the Dirichlet distribution. Due to several probabilistic and inferential properties and to the easiness of parameter interpretation, the Dirichlet distribution proves the most well-known and widespread model on the unitary simplex. However, despite its many good features, such distribution is inadequate for modeling the data portions next to the vertices of the support due to the strictness of the limiting values of its… Expand

BIVARIATE GENERALIZATION OF THE KUMMER-BETA DISTRIBUTION
In this article, we study several properties such as marginal and conditional distributions, joint moments, and mixture representation of the bivariate generalization of the Kummer-Beta distribution.Expand

Abstract : Let X sub 1, X sub 2,... be a sequence of i.i.d. random variables and S sub n = summation, j = 1 to j = n, of X sub j. If X sub 1 has a gamma distribution, (Z sub n is identically equal toExpand

The Population Dynamics of a Long-Lived Conifer (Pinus palustris)
TLDR
It is suggested that longleaf pine maintains the environment in an open state suitable for its own regeneration by transmuting a localized disturbance into a widespread disturbance (ground fires) and this regeneration pattern represents a spatial analogue to stochastic boundedness over time, and it may enhance the local persistence of longleaf Pine populations.
