Augment-and-Conquer Negative Binomial Processes [PDF]

, 2012
By developing data augmentation methods unique to the negative binomial (NB) distribution, we unite seemingly disjoint count and mixture models under the NB process framework.

Effects of the Detection Efficiency on Multiplicity Distributions

, 2013
In this paper we investigate how a finite detection efficiency affects three popular multiplicity distributions, namely the Poisson, the Binomial and the Negative Binomial distributions.

Bounds on Negative Binomial Approximation to Call Function

Revstat Statistical Journal
In this paper, we develop Stein's method for negative binomial distribution using call function defined by fz(k) = (k - z)+ = max{k - z, 0}, for k ≥ 0 and z ≥ 0.

Determination of point estimates of negative binomial distribution parameters

Vojnotehnički Glasnik, 1999
A method for determining point estimates of c and p parameters of the negative binomial distribution has been presented in the paper. This is a method of moments because the estimation of these parameters is based on the mean value m and the standard ...

A q-rious positivity

, 2010
The $q$-binomial coefficients $\qbinom{n}{m}=\prod_{i=1}^m(1-q^{n-m+i})/(1-q^i)$, for integers $0\le m\le n$, are known to be polynomials with non-negative integer coefficients.

Negative Binomial Mixed Models for Analyzing Longitudinal Microbiome Data

Frontiers in Microbiology, 2018
The metagenomics sequencing data provide valuable resources for investigating the associations between the microbiome and host environmental/clinical factors and the dynamic changes of microbial abundance over time.

Priors for Random Count Matrices Derived from a Family of Negative Binomial Processes

, 2015
We define a family of probability distributions for random count matrices with a potentially unbounded number of rows and columns. The three distributions we consider are derived from the gamma-Poisson, gamma-negative binomial, and beta-negative binomial

New robust estimators for the fixed effects negative binomial model: a simulation and real-world applications to European panel data

Frontiers in Applied Mathematics and Statistics
This study introduces a more flexible approach by employing the fixed effects negative binomial model to address challenges associated with outliers and dispersion.

Distribución espacial de Vatiga spp. (Hemiptera: Tingidae) en el cultivo de yuca

Acta Biológica Colombiana, 2016
El objetivo de este trabajo fue generar informacion acerca de cuál es el modelo de disposición espacial de Vatiga spp. en el cultivo de la yuca. Se realizaron muestreos en dos áreas comerciales de 2500 m2, divididas en 100 parcelas. Se contaron adultos y
