Non-classical properties and algebraic characteristics of negative binomial states in quantized radiation fields [PDF]

open access: yes, 1999
We study the nonclassical properties and algebraic characteristics of the negative binomial states introduced by Barnett recently. The ladder operator formalism and displacement operator formalism of the negative binomial states are found and the algebra

A continuous version of the negative binomial distribution

open access: yesStatistica, 2013
While discretization of continuous distributions have been attempted for many life distributions the reverse has hardly been attempted. The present endeavor is to establish a reverse relationship by offering a continuous counter part of a discrete ...

Comparison of different statistical models for the analysis of fracture events: findings from the Prevention of Falls Injury Trial (PreFIT)

open access: yesBMC Medical Research Methodology, 2023
Background Fractures are rare events and can occur because of a fall. Fracture counts are distinct from other count data in that these data are positively skewed, inflated by excess zero counts, and events can recur over time.

Negative Binomial and Multinomial States: probability distributions and coherent states [PDF]

open access: yes, 1996
Following the relationship between probability distribution and coherent states, for example the well known Poisson distribution and the ordinary coherent states and relatively less known one of the binomial distribution and the $su(2)$ coherent states ...

A New Neutrosophic Negative Binomial Distribution: Properties and Applications

open access: yesJournal of Mathematics, 2021
Many problems in real life exist that are full of confusion, vagueness, and ambiguity. The quantification of such issues in a scientific way is the need of time.

Group sequential designs for negative binomial outcomes

open access: yes, 2018
Count data and recurrent events in clinical trials, such as the number of lesions in magnetic resonance imaging in multiple sclerosis, the number of relapses in multiple sclerosis, the number of hospitalizations in heart failure, and the number of ...

Stein factors for negative binomial approximation in Wasserstein distance [PDF]

open access: yes, 2015
The paper gives the bounds on the solutions to a Stein equation for the negative binomial distribution that are needed for approximation in terms of the Wasserstein metric.

PERFORMA PROPORSI ZERO-INFLATION PADA REGRESI ZERO-INFLATED NEGATIVE BINOMIAL

open access: yesE-Jurnal Matematika, 2019
Tetanus Neonatorum (TN) is an infectious disease that could be prevented by immunization. East Java Province is the highest numbers of TN case in Indonesia. TN data in East Java contain overdispersion and big proportion of zero-inflation (71,05%).

On a Bivariate Poisson Negative Binomial Risk Process

open access: yesBiomath, 2014
In this paper we define a bivariate counting process as a compound Poisson process with bivariate negative binomial compounding distribution. We investigate some of its basic properties, recursion formulas and probability mass function.
