On Some Aspects of a Generalized Asymmetric Normal Distribution

Statistica, 2018
The normal and skew normal distributions are not adequate enough for modeling plurimodal data situations. In order to overcome this drawback of normal and skew normal distribution, Kumar and Anusree (2011) proposed a new class of distribution namely "the

Improved parameter estimators for the flexible extended skew-t model with extensive simulations, applications and volatility modeling

Scientific African, 2023
This study introduces a new conditional innovation density called the generalized odd generalized exponentiated skew-t (GOGEST) distribution for the generalized autoregressive conditional heteroscedasticity (GARCH) volatility models.

On statistical estimations of vehicle speed measurements [PDF]

Metrology and Measurement Systems, 2019
The accuracy of vehicle speed measured by a speedometer is analysed. The stress on the application of skew normal distribution is laid. The accuracy of measured vehicle speed depends on many error sources: construction of speedometer, measurement method,

Likelihood Inference of Nonlinear Models Based on a Class of Flexible Skewed Distributions

Abstract and Applied Analysis, 2014
This paper deals with the issue of the likelihood inference for nonlinear models with a flexible skew-t-normal (FSTN) distribution, which is proposed within a general framework of flexible skew-symmetric (FSS) distributions by combining with skew-t ...

Skew-Symmetric Generalized Normal and Generalized t Distributions

Axioms
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

An Information-Theoretic Approach for Multivariate Skew-t Distributions and Applications

Mathematics, 2021
Shannon and Rényi entropies are two important measures of uncertainty for data analysis. These entropies have been studied for multivariate Student-t and skew-normal distributions.
