Matrix-variate beta distribution [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We propose matrix-variate beta type III distribution. Several properties of this distribution including Laplace transform, marginal distribution and its relationship with matrix-variate beta type I and type II distributions are also studied.

The Beta-Gompertz Distribution [PDF]

open access: yesRevista Colombiana de Estadística, 2014
In this paper, we introduce a new four-parameter generalized version of the Gompertz model which is called Beta-Gompertz (BG) distribution. It includes some well-known lifetime distributions such as Beta-exponential and generalized Gompertz distributions

Beta Distribution-Based Cross-Entropy for Feature Selection [PDF]

open access: yesEntropy, 2019
Analysis of high-dimensional data is a challenge in machine learning and data mining. Feature selection plays an important role in dealing with high-dimensional data for improvement of predictive accuracy, as well as better interpretation of the data ...

Hepatic Fat Quantification Using Beta Distribution and a Probabilistic Neural Network in a Prepubertal Male Cohort [PDF]

open access: yesDiagnostics
Background/Objectives: High liver fat content is closely associated with hepatic disease and multiple comorbidities including cancer, diabetes and cardiovascular accidents. Therefore, accurate quantification of hepatic steatosis, especially of borderline

Two Monotonicity Results for Beta Distribution Functions. [PDF]

open access: yesEntropy (Basel)
Write pbeta(·,α,β) for the distribution function of the Beta distribution with parameters α and β. We show that α↦pbeta(α/(α+β),α,β) is decreasing and α↦pbeta(&alpha ...

Secondary Cooling Water System Control Method Based on Deep Reinforcement Learning [PDF]

open access: yesSensors
The secondary cooling water system is difficult to control because of loop coupling, thermal inertia, and strict actuator constraints. In addition, when conventional proximal policy optimization (PPO) uses Gaussian action sampling with clipping, the ...

The Confluent Hypergeometric Beta Distribution

open access: yesMathematics, 2023
The confluent hypergeometric beta distribution due to Gordy has been known since the 1990s, but not much of is known in terms of its mathematical properties.

A generalization of the beta-binomial distribution

open access: yesJournal of the Royal Statistical Society Series C: Applied Statistics, 2007
The paper describes a distribution generated by the Gaussian hypergeometric function that may be seen as a generalization of the beta-binomial distribution. It is expressed as a generalized beta mixture of a binomial distribution.

New extension of beta, Gauss and confluent hypergeometric functions

open access: yesCumhuriyet Science Journal, 2021
There are many extensions and generalizations of Gamma and Beta functions in the literature. However, a new extension of the extended Beta function B_(ζ〖, α〗_1)^(α_2;〖 m〗_1,〖 m〗_2 ) (a_1,a_2 ) was introduced and presented here because of its important ...
