An Extension of the Truncated-Exponential Skew- Normal Distribution

open access: yesMathematics, 2021
In the paper, we present an extension of the truncated-exponential skew-normal (TESN) distribution. This distribution is defined as the quotient of two independent random variables whose distributions are the TESN distribution and the beta distribution ...

COVID-19: Nothing is Normal in this Pandemic

open access: yesJournal of Epidemiology and Global Health, 2021
This manuscript brings attention to inaccurate epidemiological concepts that emerged during the COVID-19 pandemic. In social media and scientific journals, some wrong references were given to a “normal epidemic curve” and also to a “log-normal curve ...

Improving Grid-Connection Reliability and Safety of Synchronous Condensers With Start-Up Process Optimization

open access: yesIEEE Access, 2020
The new-type synchronous condenser uses the uncontrollable and irreversible freewheeling grid-connection mode during the start-up process, so that considerable rates of grid-connection failure could be observed in case of strict grid-connection ...

Statistical notes for clinical researchers: assessing normal distribution (2) using skewness and kurtosis

open access: yesRestorative Dentistry & Endodontics, 2013
As discussed in the previous statistical notes, although many statistical methods have been proposed to test normality of data in various ways, there is no current gold standard method.

Extended Generalized Sinh-Normal Distribution

open access: yesMathematics, 2021
Positively skewed data sets are common in different areas, and data sets such as material fatigue, reaction time, neuronal reaction time, agricultural engineering, and spatial data, among others, need to be fitted according to their features and maintain

On the Kullback-Leibler divergence between discrete normal distributions [PDF]

open access: yesJournal of the Indian Institute of Science (2022), 2021
Discrete normal distributions are defined as the distributions with prescribed means and covariance matrices which maximize entropy on the integer lattice support. The set of discrete normal distributions form an exponential family with cumulant function related to the Riemann theta function.

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

open access: yesChina 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
