Generalized Skew-Normal Negentropy and Its Application to Fish Condition Factor Time Series

open access: yesEntropy, 2017
The problem of measuring the disparity of a particular probability density function from a normal one has been addressed in several recent studies. The most used technique to deal with the problem has been exact expressions using information measures ...

Wiener-Hopf solution for impenetrable wedges at skew incidence [PDF]

open access: yes, 2006
A new Wiener-Hopf approach for the solution of impenetrable wedges at skew incidence is presented. Mathematical aspects are described in a unified and consistent theory for angular region problems.

Stochastic Volatility Model with Leverage and Asymmetrically Heavy-tailed Error Using GH Skew Student's t-distribution [PDF]

open access: yes
Bayesian analysis of a stochastic volatility model with a generalized hyperbolic (GH) skew Student's t-error distribution is described where we first consider an asymmetric heavy-tailness as well as leverage effects. An efficient Markov chain Monte Carlo

An Extension of the Truncated-Exponential Skew- Normal Distribution

open access: yesMathematics, 2021
In the paper, we present an extension of the truncated-exponential skew-normal (TESN) distribution. This distribution is defined as the quotient of two independent random variables whose distributions are the TESN distribution and the beta distribution ...

Analysis of Antibody Data Using Skew-normal and Skew-T Mixture Models

open access: yesRevstat Statistical Journal
Gaussian mixture models, which assume a Normal distribution for each component, are popular in antibody (or serological) data analysis to help determining antibody-positive and antibody-negative individuals.

Kullback–Leibler Divergence Measure for Multivariate Skew-Normal Distributions

open access: yesEntropy, 2012
The aim of this work is to provide the tools to compute the well-known Kullback–Leibler divergence measure for the flexible family of multivariate skew-normal distributions.

Multivariate geometric skew-normal distribution [PDF]

open access: yesStatistics, 2017
Azzalini (1985) introduced a skew-normal distribution of which normal distribution is a special case. Recently Kundu (2014) introduced a geometric skew-normal distribution and showed that it has certain advantages over Azzalini's skew-normal distribution. In this paper we discuss about the multivariate geometric skew-normal distribution. It can be used

Bounds on Rényi and Shannon Entropies for Finite Mixtures of Multivariate Skew-Normal Distributions: Application to Swordfish (Xiphias gladius Linnaeus)

open access: yesEntropy, 2016
Mixture models are in high demand for machine-learning analysis due to their computational tractability, and because they serve as a good approximation for continuous densities.

Prefeasibility Study of Photovoltaic Power Potential Based on a Skew-Normal Distribution

open access: yesEnergies, 2020
Solar energy does not always follow the normal distribution due to the characteristics of natural energy. The system advisor model (SAM), a well-known energy performance analysis program, analyzes exceedance probabilities by dividing solar irradiance ...
