Controlling factors on the global distribution of a representative marine non-cyanobacterial diazotroph phylotype (Gamma A) [PDF]

open access: yesBiogeosciences, 2022
Non-cyanobacterial diazotrophs may be contributors to global marine N2 fixation, although the factors controlling their distribution are unclear. Here, we explored what controls the distribution of the most sampled non-cyanobacterial diazotroph phylotype,

ON A NEW GENERALIZED BETA FUNCTION DEFINED BY THE GENERALIZED WRIGHT FUNCTION AND ITS APPLICATIONS

open access: yesMalaysian Journal of Computing, 2021
Various extensions of classical gamma, beta, Gauss hypergeometric and confluent hypergeometric functions have been proposed recently by many researchers. In this paper, further generalized extended beta function with some of its properties like summation

Better performance for right-skewed data using an alternative gamma model

open access: yesBMC Medical Research Methodology, 2023
Background The Maximum Likelihood Estimator (MLE) for parameters of the gamma distribution is commonly used to estimate models of right-skewed variables such as costs, hospital length of stay, and appointment wait times in Economics and Healthcare ...

The Semi-Hyperbolic Distribution and Its Applications

open access: yesStats, 2023
This paper studies a subclass of the class of generalized hyperbolic distribution called the semi-hyperbolic distribution. We obtain analytical expressions for the cumulative distribution function and, specifically, their first and second lower partial ...

Redshift distribution of gamma-ray bursts and star formation rate [PDF]

open access: yes, 2006
Aims. The redshift distribution of gamma-ray bursts collected in the BATSE Catalog is compared with the star formation rate.We aim to clarify the accordance between them. We also study the case of comoving number density of bursts monotonously increasing

Modeling Vehicle Insurance Loss Data Using a New Member of T-X Family of Distributions

open access: yesJournal of Statistical Theory and Applications (JSTA), 2020
In actuarial literature, we come across a diverse range of probability distributions for fitting insurance loss data. Popular distributions are lognormal, log-t, various versions of Pareto, log-logistic, Weibull, gamma and its variants and a generalized ...

New extension of beta, Gauss and confluent hypergeometric functions

open access: yesCumhuriyet Science Journal, 2021
There are many extensions and generalizations of Gamma and Beta functions in the literature. However, a new extension of the extended Beta function B_(ζ〖, α〗_1)^(α_2;〖 m〗_1,〖 m〗_2 ) (a_1,a_2 ) was introduced and presented here because of its important ...

Comparison of the efficiency of some Non-Parametric Methods in estimating Multivariate Linear Regression Models [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2013
Regression is one of the statistical methods and widely used in various fields of science in terms of defining clearly the relationship between the variables in the form of an equation to estimate the parameters and the strength and direction of this ...
