Statistical Treatment of Clinical Investigations in Pediatric Cardiology

open access: yesChildren, 2021
This paper describes various statistical methods used by the author during multiple studies conducted by the author. Initially, the data were scrutinized to ensure normal distribution, and expressed as mean ± standard deviation (SD) or standard error of ...

On the Folded Normal Distribution

open access: yesMathematics, 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 ...

Comparison Between Different Probability Distributions for Modeling Exchange Rate Volatility Behavior in Oil Countries for the Period 1990 – 2022

open access: yesWasit Journal for Pure Sciences
this study examines the distributional properties of exchange rate volatility for major oil-exporting developing economies from 1990-2022. Three probability distributions [ Normal, Fr'echet, and Log Normal] are compared using moment method and maximum ...

Properties of Various Entropies of Gaussian Distribution and Comparison of Entropies of Fractional Processes

open access: yesAxioms, 2023
We consider five types of entropies for Gaussian distribution: Shannon, Rényi, generalized Rényi, Tsallis and Sharma–Mittal entropy, establishing their interrelations and their properties as the functions of parameters.
