A Sample Selection Model with Skew‐normal Distribution [PDF]
Scandinavian Journal of Statistics, 2015 AbstractNon‐random sampling is a source of bias in empirical research. It is common for the outcomes of interest (e.g. wage distribution) to be skewed in the source population. Sometimes, the outcomes are further subjected to sample selection, which is a type of missing data, resulting in partial observability. Thus, methods based on complete cases for

On the Canonical Form of Scale Mixtures of Skew-Normal Distributions
Statistica, 2020 The canonical form of scale mixtures of multivariate skew-normal distribution is defined, emphasizing its role in summarizing some key properties of this class of distributions.

The Family of Log-Skew-Normal Alpha-Power Distributions using Precipitation Data
Revista Colombiana de Estadística, 2013 We present a new set of distributions for positive data based on a skew-normal alpha-power (PSN) model including a new parameter which in turn makes the log-skew-normal alpha-power (LPSN) model more flexible than both the log-normal (LN) model and log ...

The standard error of the Pearson skew [PDF]
Tutorials in Quantitative Methods for Psychology, 2015 The Pearson skew is a measure of asymmetry of a distribution, based on the difference between the mean and the median of a distribution. Here we show how to calculate the Pearson skew, estimate its standard error and the confidence interval.

Introduction to the Theme Issue: The Skew-Normal and Related Distributions
Statistica, 2020 This theme issue on the skew-Normal and related distributions is motivated by the workshop held on November 6th, 2017 in memory of Antonella Capitanio, one year after her premature loss.

Skew-normal shocks in the linear state space form DSGE model [PDF]
Observed macroeconomic data – notably GDP growth rate, inflation and interest rates – can be, and usually are skewed. Economists attempt to fit models to data by matching first and second moments or co-moments, but skewness is usually neglected. It is so

Construction and Applications of a Composite Model Based on Skew-Normal and Skew-t Distributions
EconometricsFinancial return distributions often exhibit central asymmetry and heavy-tailed extremes, challenging standard parametric models. We propose a novel composite distribution integrating a skew-normal center with skew-t tails, partitioning the support into ...

Some Information Properties of Order Statistics of Skew-normal Distribution
Revstat Statistical JournalThe skew-normal distribution and some of its extensions have been considered in the last two decades in view of distribution theory and the associated properties. However, less attention has been paid to other aspects of this family of distributions. In
