Matrix-variate beta distribution [PDF]
International 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.

On the Noncentral Beta-Distribution [PDF]
The Annals of Mathematical Statistics, 1955 A computing formula for the noncentral beta-distribution recently published by Nicholson is simplified. A table of figurate numbers is provided to facilitate the use of the simplified formula. It is compared for ease of use with the method of Tang in several situations.

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

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

A New 3-Parameter Bounded Beta Distribution: Properties, Estimation, and Applications
Axioms, 2022 This study presents a new three-parameter beta distribution defined on the unit interval, which can have increasing, decreasing, left-skewed, right-skewed, approximately symmetric, bathtub, and upside-down bathtub shaped densities, and increasing, U, and

Inflated beta distributions [PDF]
Statistical 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 ...

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

The beta Gumbel distribution [PDF]
Mathematical 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.

New extension of beta, Gauss and confluent hypergeometric functions
Cumhuriyet 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 ...
