Modelling health scores with the skew-normal distribution [PDF]

open access: yes, 2009
Health care interventions which use quality of life or health scores often provide data which are skewed and bounded. The scores are typically formed by adding up responses to a number of questions. Different questions might have different weights, but

Stochastic orders of log-epsilon-skew-normal distributions

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
The log-epsilon-skew-normal distributions family is generalized class of log-normal distribution. Is widely used to model non-negative data in many areas of applied research.

Some Statistical Aspects of the Truncated Multivariate Skew-t Distribution

open access: yesMathematics, 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.

Skew-Symmetric Generalized Normal and Generalized t Distributions

open access: yesAxioms
In this paper, we introduce the skew-symmetric generalized normal and the skew-symmetric generalized t distributions, which are skewed extensions of symmetric special cases of generalized skew-normal and generalized skew-t distributions, respectively. We

Surprising Implications of Differences in Locations Versus Differences in Means

open access: yesMethodology, 2023
Social science researchers depend on differences in means between experimental and control conditions to draw substantive conclusions. However, an alternative is to use differences in locations. For normal distributions, means and locations are the same,

An Extension of the Epsilon-Skew-Normal Distribution

open access: yesCommunications in Statistics - Theory and Methods, 2010
This article is related with the probabilistic and statistical properties of an parametric extension of the so-called epsilon-skew-normal (ESN) distribution introduced by Mudholkar and Hutson (2000), which considers an additional shape parameter in order to increase the flexibility of the ESN distribution.

Skew Incidence on Concave Wedge With Anisotropic Surface Impedance [PDF]

open access: yes, 2012
The diffraction of a plane wave at skew incidence by an arbitrary-angled concave wedge with anisotropic impedance faces is studied. Concave wedges are of interest in wireless propagation models, in particular on modeling buildings and reflectors.

A Method to Simulate the Skew Normal Distribution

open access: yesApplied Mathematics, 2014
A new method is developed to simulate the skew normal distribution. The result is interesting from a practical as well as a theoretical viewpoint. The new method is simple to program and is more efficient than the standard method of simulation by acceptance-rejection method.

Resampling Techniques for Estimating the Parameters of Grubbs Model with Asymmetric Heavy-Tailed Distributions [PDF]

open access: yesThe Egyptian Statistical Journal, 2017
In this paper, three resampling techiques are considered, namely, bootstrap, jack-knife and jackknife after bootstrap. The main objective is to study the performance of these techniques for maximum likehood estimation for the parameters using expectation
