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 ...

Inference for grouped data with a truncated skew-Laplace distribution [PDF]

, 2010
The skew-Laplace distribution has been used for modelling particle size with point observations. In reality, the observations are truncated and grouped (rounded).

A New Family of Distributions Based on Proportional Hazards

Mathematics, 2022
In this article, we introduce a new family of symmetric-asymmetric distributions based on skew distributions and on the family of order statistics with proportional hazards.

On an Absolute Autoregressive Model and Skew Symmetric Distributions

Statistica, 2020
By exploiting the connection between a popular construction of a well-known skew-normal distribution and an absolute autoregressive process, we show how the stochastic process approach can lead to other skew symmetric distributions, including a skew ...

Alpha-skew-normal distribution [PDF]

Proyecciones (Antofagasta), 2011
The main object of this paper is to introduce an alternative form of generate asymmetry in the normal distribution that allows to fit unimodal and bimodal data sets. Basic properties of this new distribution, such as stochastic representation, moments, maximum likelihood and the singularity of the Fisher information matrix are studied.
