On the Folded Normal Distribution [PDF]

Mathematics, 2014
The characteristic function of the folded normal distribution and its moment function are derived. The entropy of the folded normal distribution and the Kullback–Leibler from the normal and half normal distributions are approximated using Taylor series ...

Approximate skew normal distribution

Journal of Advanced Research, 2010
We propose a new approximate skew normal distribution, it is easy to calculate, convenient, mathematically tractable and is in a closed form. It is particularly useful when the probability density function occurs in an expression to be used for further ...

The unintended impact of housing provident fund on income inequality in urban China

China Economic Quarterly International, 2021
We use the China Household Income Project (CHIP) data to evaluate the impact of the Housing Provident Fund (HPF) on income inequality in urban China. We find that urban residents differ significantly in their accessibility to and intensity of utilization

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.

Application of python libraries for variance, normal distribution and Weibull distribution analysis in diagnosing and operating production systems

Diagnostyka, 2021
The use of statistical methods in the diagnosis of production processes dates back to the beginning of the 20th century. Widespread computerization of processes made enterprises face the challenge of processing large sets of measurement data. The growing

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.
