evgam: An R Package for Generalized Additive Extreme Value Models

open access: yesJournal of Statistical Software, 2022
This article introduces the R package evgam. The package provides functions for fitting extreme value distributions. These include the generalized extreme value and generalized Pareto distributions.

Generalized Universality for TMD Distribution Functions

open access: yes, 2012
Azimuthal asymmetries in high-energy processes, most pronounced showing up in combination with single or double (transverse) spin asymmetries, can be understood with the help of transverse momentum dependent (TMD) parton distribution and fragmentation ...

Non-Linear Langevin and Fractional Fokker-Planck Equations for Anomalous Diffusion by Levy Stable Processes [PDF]

open access: yes, 2018
The~numerical solutions to a non-linear Fractional Fokker--Planck (FFP) equation are studied estimating the generalized diffusion coefficients. The~aim is to model anomalous diffusion using an FFP description with fractional velocity derivatives and ...

Orbital Angular Momentum and Generalized Transverse Momentum Distribution [PDF]

open access: yes, 2015
We show that, when boosted to the infinite momentum frame, the quark and gluon orbital angular momentum operators defined in the nucleon spin sum rule of X. S. Chen et al.

On a Generalized Lindley Distribution

open access: yesStatistica, 2017
Nedjar and Zeghdoudi (2016) studied various properties of a distribution which they claim to have introduced. Here, we point out that the distribution is a particular case of at least two known distributions.

Generating generalized distributions from dynamical simulation [PDF]

open access: yesThe Journal of Chemical Physics, 2003
We present a general molecular-dynamics simulation scheme, based on the Nosé thermostat, for sampling from arbitrary phase space distributions. We formulate numerical methods based on both Nosé–Hoover and Nosé–Poincaré thermostats for two specific classes of distributions; namely, those that are functions of the system Hamiltonian and those for which ...

Sufficient and Necessary Conditions for Generalized Distribution Series on Comprehensive Subclass of Analytic Functions

open access: yesMathematics
In this paper, we demonstrate a relationship between a generalized distribution series and a comprehensive subclass of analytic functions. The primary aim of this study is to determine a necessary and sufficient condition for the generalized distribution

A Generalized Skew Logistic Distribution

open access: yesRevstat Statistical Journal, 2013
In this paper, we introduce a generalized skew logistic distribution that contains the usual skew logistic distribution as a special case. Several mathematical properties of the distribution are discussed like the cumulative distribution function and ...

Universality for generalized Wigner matrices with Bernoulli distribution [PDF]

open access: yes, 2010
The universality for the eigenvalue spacing statistics of generalized Wigner matrices was established in our previous work \cite{EYY} under certain conditions on the probability distributions of the matrix elements.

The Exponentiated Generalized Gumbel Distribution

open access: yesRevista Colombiana de Estadística, 2015
A class of univariate distributions called the exponentiated generalized class was recently proposed in the literature. A four-parameter model within this class named the exponentiated generalized Gumbel distribution is defined.
