Moments of the Negative Multinomial Distribution

open access: yesMathematical and Computational Applications, 2023
The negative multinomial distribution appears in many areas of applications such as polarimetric image processing and the analysis of longitudinal count data.

Compound Power Series Distribution with Negative Multinomial Summands

open access: yesRevstat Statistical Journal, 2022
The paper considers a multivariate distribution whose coordinates are compounds. The number of the summands is itself also a multivariate compound with one and the same univariate Power series distributed number of summands and negative multinomially ...

Occupancy Statistics and Entropy in Bose Systems [PDF]

open access: yesEntropy
In this work, we compare three formulations of thermodynamic entropy for a non-interacting bosonic gas: (i) the grand-canonical Bose–Einstein entropy, (ii) the finite-N canonical entropy obtained from the exact partition function (Ziff, Uhlenbeck, and ...

Comparative poisson clinical trials of multiple experimental treatments vs a single control using the negative multinomial distribution. [PDF]

open access: yesStat Med, 2021
AbstractThis paper introduces a method which conditions on the number of events that occur in the control group to determine rejection regions and power for comparative Poisson trials with multiple experimental treatment arms that are each compared to one control arm.

A Characterization of the Negative Multinomial Distribution [PDF]

open access: yes, 1981
This paper deals with a characterization of the negative multinomial distribution. It is based on the assumption that the conditional distribution of two random vectors is multivariate inverse hypergeometric. It makes use essentially of a multivariate analogue of a condition known in the literature as the Rao-Rubin condition.

Unequal access: cross-sectional associations of deprivation, racial composition and independent and joint cannabis and alcohol outlet densities among Michigan census block groups [PDF]

open access: yesBMJ Public Health
Introduction Cannabis and alcohol outlets may independently and jointly influence the health of those in their surrounding neighbourhoods. State and local policy determines the establishment of cannabis and alcohol outlets in Michigan, potentially ...

Estimating effective reproduction number revisited

open access: yesInfectious Disease Modelling, 2023
Accurately estimating the effective reproduction number is crucial for characterizing the transmissibility of infectious diseases to optimize interventions and responses during epidemic outbreaks. In this study, we improve the estimation of the effective

Correlations in Compositional Data without Log Transformations

open access: yesAxioms, 2023
This article proposes a method for determining the p-value of correlations in compositional data, i.e., those data that arise as a result of dividing original values by their sum.

Multinomial Probability Distribution and Quantum Deformed Algebras [PDF]

open access: yes, 2023
An examination is conducted on the multinomial coefficients derived from generalized quantum deformed algebras, and on their recurrence relations. The R(p, q)-deformed multinomial probability distribution and the negative R(p, q)-deformed multinomial ...
