Negative binomial and multinomial states: Probability distributions and coherent states [PDF]

open access: yesJournal of Mathematical Physics, 1997
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, we propose interpretation of su(1,1) and su(r,1) coherent states in terms of probability theory.

q-Multinomial and negativeq-multinomial distributions

open access: yesCommunications in Statistics - Theory and Methods, 2020
The notion of a Bernoulli trial is extended, by introducing recursively different kinds (ranks, levels) of success and failure, to a Bernoulli trial with chain-composite success (or failure).

Asymptotic comparison of negative multinomial and multivariate normal experiments [PDF]

open access: yes, 2023
This note presents a refined local approximation for the logarithm of the ratio between the negative multinomial probability mass function and a multivariate normal density, both having the same mean-covariance structure.

Compound negative binomial distribution with negative multinomial summands

open access: yesAIP Conference Proceedings, 2016
The class of Negative Binomial distributions seems to be introduced by Greenwood and Yule in 1920. Due to its wide spread application, investigations of distributions, closely related with it will be always contemporary. Bates, Neyman and Wishart introduce Negative Multinomial distribution.

Variable Selection in General Multinomial Logit Models [PDF]

open access: yes, 2012
The use of the multinomial logit model is typically restricted to applications with few predictors, because in high-dimensional settings maximum likelihood estimates tend to deteriorate.

Modelling Negative Binomial as a substitute model to Poisson for raters agreement on ordinal scales with sparse data [PDF]

open access: yes, 2004
The Poisson distribution has been widely used for modelling rater agreement using loglinear models. Mostly in all life or social science researches, subjects are being classified into categories by rater, interviewers or observers and most of these ...

Transference kinetics of radioactive nuclide zirconium-95 in broadbean-soil system

open access: yes浙江大学学报. 农业与生命科学版, 2003
The dynamics of transportation, accumulation, disappearance and distribution of 95Zr in the broadbean- soil system was studied by isotope-tracer technique, and the fitting equation was established by application of the closed two-compartment model and ...

Product Line Pricing under Marginal Moment Model with Network Effect

open access: yesComplexity, 2019
The complex network effect of the product exhibits has a significant impact on the product line optimization design. The multinomial logit (MNL) model which is used to simulate consumer choice behavior is applied in most of product line optimization ...

An Observational Case-Control Study to Determine Human Immunodeficiency Virus and Host Factor Influence on Biomarker Distribution and Serodiagnostic Potential in Adult Pulmonary Tuberculosis

open access: yesTropical Medicine and Infectious Disease, 2019
Influence of host factors, including human immunodeficiency virus (HIV) co-infection, on the distribution and diagnostic potential of previously evaluated biomarkers of pulmonary tuberculosis (PTB), such as anti-antigen 60 (A60) immunoglobulin (Ig) G ...
