The right tail exponent of the Tracy-Widom-beta distribution [PDF]
Ann. Inst. H. Poincar\'e Probab. Statist. Volume 49, Number 4
(2013), 915-1231, 2011 The Tracy-Widom beta distribution is the large dimensional limit of the top eigenvalue of beta random matrix ensembles. We use the stochastic Airy operator representation to show that as a tends to infinity the tail of the Tracy Widom distribution ...

Parametrizing the exoplanet eccentricity distribution with the Beta distribution [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2013 Abstract It is suggested that the distribution of orbital eccentricities for extrasolar planets is well described by the Beta distribution. Several properties of the Beta distribution make it a powerful tool for this purpose. For example, the Beta distribution can reproduce a diverse range of probability density functions (PDFs) using ...

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

Using the Beta distribution in group-based trajectory models. [PDF]
BMC Med Res Methodol, 2018 BackgroundWe demonstrate an application of Group-Based Trajectory Modeling (GBTM) based on the beta distribution. It is offered as an alternative to the normal distribution for modeling continuous longitudinal data that are poorly fit by the normal ...

Neutrosophic Beta Distribution with Properties and Applications [PDF]
Neutrosophic Sets and Systems, 2021 This research is an extension of classical statistics distribution theory as the theory did not deal with the problems having ambiguity, impreciseness, or indeterminacy.

Bernstein-type bounds for beta distribution [PDF]
Modern Stochastics: Theory and Applications, 2023 This work obtains sharp closed-form exponential concentration inequalities of Bernstein type for the ubiquitous beta distribution, improving upon sub-Gaussian and sub-gamma bounds previously studied in this context.

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 ...

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.

Probability Densities of the effective neutrino masses $m_{\beta }$ and $m_{\beta \beta}$ [PDF]
, 2017 We compute the probability densities of the effective neutrino masses $m_{\beta }$ and $m_{\beta \beta}$ using the Kernel Density Estimate (KDE) approach applied to a distribution of points in the $(m_{\min}, m_{\beta\beta })$ and $(m_{\beta }, m_{\beta ...
