Matrix‐variate beta distribution [PDF]

open access: goldInternational 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

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

The Beta Generalized Exponential Distribution [PDF]

open access: yesJournal of Statistical Computation and Simulation, 2008
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.

Inflated beta distributions [PDF]

open access: yesStatistical Papers, 2008
This paper considers the issue of modeling fractional data observed in the interval [0,1), (0,1] or [0,1]. Mixed continuous-discrete distributions are proposed. The beta distribution is used to describe the continuous component of the model since its density can have quite diferent shapes depending on the values of the two parameters that index the ...

Beta trigonometric distributions [PDF]

open access: yesPortuguese Economic Journal, 2006
Beta distributions are popular models for economic data. In this paper, six new distributions are introduced which generalize the standard beta distribution. These distributions involve the trigonometric functions, sine and cosine. Expressions are derived for their analytical shapes, nth moments, method of moments estimators, maximum likelihood ...

The beta Gumbel distribution [PDF]

open access: yesMathematical Problems in Engineering, 2004
The Gumbel distribution is perhaps the most widely applied statistical distribution for problems in engineering. In this paper, we introduce a generalization—referred to as the beta Gumbel distribution—generated from the logit of a beta random variable. We provide a comprehensive treatment of the mathematical properties of this new distribution.

The beta power distribution [PDF]

open access: yesBrazilian Journal of Probability and Statistics, 2012
The power distribution is defined as the inverse of the Pareto distribution. We study in full detail a distribution so-called the beta power distribution. We obtain analytical forms for its probability density and hazard rate functions. Explicit expressions are derived for the moments, probability weighted moments, moment generating function, mean ...

Convolution of beta prime distribution

open access: yesTransactions of the American Mathematical Society, 2022
We establish some identities in law for the convolution of a beta prime distribution with itself, involving the square root of beta distributions. The proof of these identities relies on transformations on generalized hypergeometric series obtained via Appell series of the first kind and Thomae’s relationships for

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.

The Beta‐Half‐Cauchy Distribution [PDF]

open access: yesJournal 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.
