The Beta-Binomial Distribution [PDF]

open access: yes, 2023
The beta-binomial distribution can be thought of as a binomial distribution where the probability of success in each trial is not fixed but follows a beta distribution. It is often used to capture correlation in a sequence of Bernoulli trials or to model over-dispersion.

Double Generalized Beta-Binomial and Negative Binomial Regression Models [PDF]

open access: yesRevista Colombiana de Estadística, 2017
Overdispersion is a common phenomenon in count datasets, that can greatly affect inferences about the model. In this paper develop three joint mean and dispersion regression models in order to fit overdispersed data.

Modeling Stochastic Crop Yield Expectations with a Limiting Beta Distribution [PDF]

open access: yesJournal of Agricultural and Resource Economics, 2011
The use of plausible stochastic price processes in price risk analysis has allowed advances not seen in crop yield risk analysis. This study develops a stochastic process for yield modeling and risk management.

A Mechanistic Beta-Binomial Probability Model for mRNA Sequencing Data. [PDF]

open access: yesPLoS ONE, 2016
A main application for mRNA sequencing (mRNAseq) is determining lists of differentially-expressed genes (DEGs) between two or more conditions. Several software packages exist to produce DEGs from mRNAseq data, but they typically yield different DEGs ...

Applications of Beta Negative Binomial Distribution and Laguerre Polynomials on Ozaki Bi-Close-to-Convex Functions

open access: yesAxioms, 2022
In the present paper, due to beta negative binomial distribution series and Laguerre polynomials, we investigate a new family FΣ(δ,η,λ,θ;h) of normalized holomorphic and bi-univalent functions associated with Ozaki close-to-convex functions.

Beta–Binomial and Overdispersion with Exchange of the Sample Size over the Probability Interval [0, 1] with Applications

open access: yesPasser Journal, 2020
The beta-binomial model that is generated by a simple mixture model has been commonly applied in the health, physical, and social sciences. In clinical and public health, overdispersion occurs due to biological variation between the subjects of interest.

Exact Posterior distribution of risk ratio in the Kumaraswamy–Binomial model

open access: yesComptes Rendus. Mathématique, 2023
In categorical data analysis, the $2\times 2$ contingency tables are commonly used to assess the association between groups and responses, this is achieved by using some measures of association, such as the contingency coefficient, odds ratio, risk ...

Beta-binomial distribution.

open access: yes, 2023
β-binomial distributions for identical mean: μ, μ1 = 12 but different standard deviations: σ = 3, σ1 = 5. The dotted lines signifies the mean of the distribution where as the shaded area is the standard deviation across 5 trials. (PNG)

Bonus-Malus Premiums Based on Claim Frequency and the Size of Claims

open access: yesRisks, 2022
The bonus-malus system (BMS) is one of the most widely used tools in merit-rating automobile insurance, with the primary goal of ensuring that fair premiums are paid by all policyholders. The traditional BMS is dependent only on the claim frequency. Thus,
