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.

Efficient algorithms for the inversion of the cumulative central beta distribution [PDF]
Numerical Algorithms, 2016 Accurate and efficient algorithms for the inversion of the cumulative central beta distribution are described. The algorithms are based on the combination of a fourth-order fixed point method with good non-local convergence properties (the Schwarzian ...

Using the beta distribution to analyse plant cover data
Journal of Ecology, 2019 Most plant species are spatially aggregated. Local demographic and ecological processes (e.g. vegetative growth and limited seed dispersal) result in a clustered spatial pattern within an environmentally homogenous area.

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)

Distribution of spectral linear statistics on random matrices beyond the large deviation function -- Wigner time delay in multichannel disordered wires [PDF]
, 2016 An invariant ensemble of $N\times N$ random matrices can be characterised by a joint distribution for eigenvalues $P(\lambda_1,\cdots,\lambda_N)$. The study of the distribution of linear statistics, i.e.

Beta trigonometric distributions [PDF]
Portuguese 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 ...

Some results on non-central beta distributions
Statistica, 2015 In this paper a new non-central beta distribution is defined. Several properties are derived (including various representations and moments expressions) both for the new and the standard non-central beta distribution, showing a greater tractability and ...
