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.

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 ...

An Extension of the Truncated-Exponential Skew- Normal Distribution

Mathematics, 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 ...

The Exponential-Centred Skew-Normal Distribution [PDF]

Symmetry, 2020
Data from some research fields tend to exhibit a positive skew. For example, in experimental psychology, reaction times (RTs) are characterised as being positively skewed. However, it is not unlikely that RTs can take a normal or, even, a negative shape. While the Ex-Gaussian distribution is suitable to model positively skewed data, it cannot cope with

Some Statistical Aspects of the Truncated Multivariate Skew-t Distribution

Mathematics, 2022
The multivariate skew-t distribution plays an important role in statistics since it combines skewness with heavy tails, a very common feature in real-world data.

Inference and Local Influence Assessment in a Multifactor Skew-Normal Linear Mixed Model

Mathematics, 2022
This work considers a multifactor linear mixed model under heteroscedasticity in random-effect factors and the skew-normal errors for modeling the correlated datasets.

An Alternative to the Log-Skew-Normal Distribution: Properties, Inference, and an Application to Air Pollutant Concentrations

Mathematics, 2022
In this study, we consider an alternative to the log-skew-normal distribution. It is called the modified log-skew-normal distribution and introduces greater flexibility in the skewness and kurtosis parameters.

Quantile Estimation Using the Log-Skew-Normal Linear Regression Model with Application to Children’s Weight Data

Mathematics, 2023
In this article, we establish properties that relate quantiles of the log-skew-normal distribution to its parameters, allowing us to investigate the relationship between quantiles of a positive skewed response variable and a set of explanatory variables ...
