On The Gamma-Half Normal Distribution and Its Applications [PDF]
Journal of Modern Applied Statistical Methods, 2013 A new distribution, the gamma-half normal distribution, is proposed and studied. Various structural properties of the gamma-half normal distribution are derived. The shape of the distribution may be unimodal or bimodal. Results for moments, limit behavior, mean deviations and Shannon entropy are provided. To estimate the model parameters, the method of

A Regression Model for Positive Data Based on the Slashed Half-Normal Distribution
Revstat Statistical Journal, 2021 In this paper, we discuss several aspects about the slashed half-normal distribution. We reparameterize the model based on the mean and we perform comparisons with well-known regression models for positive data.

On the Folded Normal Distribution [PDF]
Mathematics, 2014 The characteristic function of the folded normal distribution and its moment function are derived. The entropy of the folded normal distribution and the Kullback–Leibler from the normal and half normal distributions are approximated using Taylor series ...

Bayesian inference for the half-normal and half-t distributions [PDF]
, 2005 In this article we consider approaches to Bayesian inference for the half-normal and half-t distributions. We show that a generalized version of the normal-gamma distribution is conjugate to the half-normal likelihood and give the moments of this new distribution. The bias and coverage of the Bayesian posterior mean estimator of the halfnormal location

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 ...

Mathematics, 2023 This paper proposes, for the first time, the use of an asymmetric positive and heavy-tailed distribution in a cure rate model context. In particular, it introduces a cure-rate survival model by assuming that the time-to-event of interest follows a slash ...

Kuwait Journal of Science, 2022 Recent years have shown growth in the potential applications of extensions of skew and half-normal distributions. In this paper, we provide and study, in detail, a flexible and extended class of such distributions. The developed distribution has a scale
