Multivariate gamma distributions [PDF]

open access: yesElectronic Communications in Probability, 2014
A representation is given for a large class of n-dimensional multivariate gamma random variables as defined by Verre-Jones. In particular, the probability density functions of all 2-dimensional gamma random variables are given explicitly and it is shown how to obtain the probability density functions of all 3-dimensional gamma random variables.

Angular characteristics of multipath propagation in an indoor industrial environment

open access: yesIET Microwaves, Antennas & Propagation, 2021
The characteristics of multipath components (MPCs) are addressed in an industrial environment at 1.3 GHz by means of measurements with a multidimensional channel sounder.

Modelling Spray Pressure Effects on Droplet Size Distribution from Agricultural Nozzles

open access: yesApplied Sciences, 2021
For spray applications, drop size is the most important feature as it affects all aspects of a phytosanitary treatment: biological efficacy, environmental pollution, and operator safety.

Anisotropy in the sky distributions of the short and intermediate gamma-ray bursts: Breakdown of the cosmological principle? [PDF]

open access: yes, 2009
After the discovery of the anisotropy in the sky-distribution of intermediate gamma-ray bursts recently also the distribution of the short gamma-ray bursts is proven to be anisotropic.

Statistical distributions of optimal global alignment scores of random protein sequences

open access: yesBMC Bioinformatics, 2005
Background The inference of homology from statistically significant sequence similarity is a central issue in sequence alignments. So far the statistical distribution function underlying the optimal global alignments has not been completely determined ...

A Simulation-Based Testing of Difference in the Means of Gamma-Distributed Positive Quantities

open access: yesApplied Sciences, 2023
This paper presents a simulation-based testing procedure that can be easily applied by practitioners who try to determine whether two gamma-distributed variables have the same expected values. From both theoretical and practical points of view, the gamma

Modelagem da ocorrência e da quantidade de chuva em Piracicaba Modeling of occurrence and rain amount in Piracicaba

open access: yesScientia Agricola, 1995
É proposto um modelo para descrever chuva diária de Piracicaba-SP em termos da sua ocorrência e da quantidade. Ambos, a ocorrência de dias com e sem chuva, quando considerados como seqüências de 31 dias a partir de determinada data, puderam ser bem ...

Bimatrix variate Kummer-gamma distribution

open access: yesResults in Applied Mathematics, 2021
In this article, we propose a bimatrix variate Kummer-gamma distribution. Several properties of this distribution including moment generating function, marginal and conditional distributions, moments are also derived.
