A New Family of Distributions Based on Proportional Hazards
Mathematics, 2022 In this article, we introduce a new family of symmetric-asymmetric distributions based on skew distributions and on the family of order statistics with proportional hazards.

The Extended Half-Skew Normal Distribution
Mathematics, 2022 A new class of densities for modelling non-negative data, which is based on the skew-symmetric family of distributions proposed by Azzalini is introduced.We focus on the model generated by the skew-normal distribution, called Extended Half Skew-Normal ...

Revstat Statistical Journal, 2021 Skewed probit regression is but one example of a statistical model that generalizes a simpler model, like probit regression. All skew-symmetric distributions and link functions arise from symmetric distributions by incorporating a skewness parameter ...

Riemannian Gaussian distributions, random matrix ensembles and diffusion kernels
Nuclear Physics B, 2021 We show that the Riemannian Gaussian distributions on symmetric spaces, introduced in recent years, are of standard random matrix type. We exploit this to compute analytically marginals of the probability density functions.

Coming Together of Bayesian Inference and Skew Spherical Data
Frontiers in Big Data, 2022 This paper presents Bayesian directional data modeling via the skew-rotationally-symmetric Fisher-von Mises-Langevin (FvML) distribution. The prior distributions for the parameters are a pivotal building block in Bayesian analysis, therefore, the impact ...

On an Absolute Autoregressive Model and Skew Symmetric Distributions
Statistica, 2020 By exploiting the connection between a popular construction of a well-known skew-normal distribution and an absolute autoregressive process, we show how the stochastic process approach can lead to other skew symmetric distributions, including a skew ...

Multivariate Asymmetric Distributions of Copula Related Random Variables
Austrian Journal of Statistics, 2023 It is known that normal distribution plays an important role in analysing symmetric data. However, this symmetric assumption may not hold in many real word and in such cases, asymmetric distribution, including skew normal distribution, are known as ...

Further Results on a Class of Distributions which Includes the Normal Ones – Looking Back
Statistica, 2020 The author’s 1986 paper with the same title is reprinted here alongside some comments and corrections. The original abstract, here translated in English, was as follows: "Some further results are presented concerning a class of density functions already ...

Properties and Applications of a New Family of Skew Distributions
Mathematics, 2021 We introduce two families of continuous distribution functions with not-necessarily symmetric densities, which contain a parent distribution as a special case.
