The Beta-Gompertz Distribution
Revista 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.

ON A NEW GENERALIZED BETA FUNCTION DEFINED BY THE GENERALIZED WRIGHT FUNCTION AND ITS APPLICATIONS
Malaysian Journal of Computing, 2021 Various extensions of classical gamma, beta, Gauss hypergeometric and confluent hypergeometric functions have been proposed recently by many researchers. In this paper, further generalized extended beta function with some of its properties like summation

The beta generalized exponential distribution [PDF]
Journal of Statistical Computation and Simulation, 2010 We introduce the beta generalized exponential distribution that includes the beta exponential and generalized exponential distributions as special cases. We provide a comprehensive mathematical treatment of this distribution. We derive the moment generating function and the $r$th moment thus generalizing some results in the literature.

Stochastic Extreme Wind Speed Modeling and Bayes Estimation under the Inverse Rayleigh Distribution
Applied Sciences, 2020 Inverse Rayleigh probability distribution is shown in this paper to constitute a valid model for characterization and estimation of extreme values of wind speed, thus constituting a useful tool of wind power production evaluation and mechanical safety of

The Beta‐Half‐Cauchy Distribution [PDF]
Journal of Probability and Statistics, 2011 On the basis of the half‐Cauchy distribution, we propose the called beta‐half‐Cauchy distribution for modeling lifetime data. Various explicit expressions for its moments, generating and quantile functions, mean deviations, and density function of the order statistics and their moments are provided.

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

A Generalization of the Beta-Distribution [PDF]
The Annals of Mathematical Statistics, 1959 A class of distributions is defined and studied which includes as particular cases (cf. Section 13) the ordinary $\beta$-distribution, the (univariate) triangular distribution, the uniform distribution over any nondegenerate simplex, and a continuous range of other distributions over such a simplex, called basic $\beta$-distributions (Section 6) and ...
