Approximate skew normal distribution

open access: yesJournal 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 ...

Galactic Subsystems on the Basis of Cumulative Distribution of Space Velocities [PDF]

open access: yesSerbian Astronomical Journal, 2008
A sample containing $4,614$ stars with available space velocities and high-quality kinematical data from the Arihip Catalogue is formed. For the purpose of distinguishing galactic subsystems the cumulative distribution of space velocities is studied ...

(Generalized) Maximum Cumulative Direct, Residual, and Paired Φ Entropy Approach

open access: yesEntropy, 2020
A distribution that maximizes an entropy can be found by applying two different principles. On the one hand, Jaynes (1957a,b) formulated the maximum entropy principle (MaxEnt) as the search for a distribution maximizing a given entropy under some given ...

On a Logistic Approximation to the Normal and Other Cumulative Distribution Functions

open access: yesRecoletos Multidisciplinary Research Journal, 2014
This paper proposes an approach that maintains the simplicity of various approximations as well as having a closed- form algebraic inverse yet easily generalizable to the approximation of other cumulative distribution functions.

Computing the Stationary Distribution of Queueing Systems with Random Resource Requirements via Fast Fourier Transform

open access: yesMathematics, 2020
Queueing systems with random resource requirements, in which an arriving customer, in addition to a server, demands a random amount of resources from a shared resource pool, have proved useful to analyze wireless communication networks.

Nonlocal Probability Theory: General Fractional Calculus Approach

open access: yesMathematics, 2022
Nonlocal generalization of the standard (classical) probability theory of a continuous distribution on a positive semi-axis is proposed. An approach to the formulation of a nonlocal generalization of the standard probability theory based on the use of ...
