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 as special sub-models.

The Confluent Hypergeometric Beta Distribution [PDF]

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 [PDF]

open access: yesJournal of the Royal Statistical Society Series C: Applied Statistics, 2007
SummaryThe 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. This new mixing distribution allows the existence of a mode and an antimode, which is very useful for fitting some ...

On the maximum likelihood estimator in the generalized beta regression model [PDF]

open access: yesOpuscula Mathematica, 2012
The subject of this article is to present the beta - regression model, where we assume that one parameter in the model is described as a combination of algebraically independent continuous functions.

Interval Prediction Method for Wind Speed Based on ARQEA Optimized by Beta Distribution and SWLSTM

open access: yesFrontiers in Energy Research, 2022
The interval prediction of wind speed is crucial for the economic and safe operation of wind farms. To overcome the probability density function parameter optimization and long-term correlation of time series problems in an interval prediction method, a ...

Some generalised extended incomplete beta functions and applications

open access: yesJournal of New Results in Science, 2022
This paper introduces generalised incomplete beta functions defined by the generalised beta function. Firstly, we provide some of the generalised beta function's basic properties, such as integral representations, summation formulas, Mellin transform ...

A Cuckoo Search Algorithm Using Improved Beta Distributing and Its Application in the Process of EDM

open access: yesCrystals, 2021
Lévy flights random walk is one of key parts in the cuckoo search (CS) algorithm to update individuals. The standard CS algorithm adopts the constant scale factor for this random walk. This paper proposed an improved beta distribution cuckoo search (IBCS)

Beta Bessel distributions [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
Three new distributions on the unit interval [0, 1] are introduced which generalize the standard beta distribution. These distributions involve the Bessel function. Expression is derived for their shapes, particular cases, and the nth moments. Estimation by the method of maximum likelihood and Bayes estimation are discussed.

Statistical Modeling of Fine Sediments Dredged Using a Variable Area Dredging Suction Head to Improve Water Quality

open access: yesHydrology, 2021
The changing climate affects the agricultural lands, and, in turn, the changes in agricultural lands alter the watershed. A major concern regarding waterbodies is the increased sedimentation rates due to climate change.

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 ...
