DREAMSeq: An Improved Method for Analyzing Differentially Expressed Genes in RNA-seq Data

open access: yesFrontiers in Genetics, 2018
RNA sequencing (RNA-seq) has become a widely used technology for analyzing global gene-expression changes during certain biological processes. It is generally acknowledged that RNA-seq data displays equidispersion and overdispersion characteristics ...

Adoption intensity of soil and water conservation practices by smallholders: evidence from Northern Ghana

open access: yesBio-based and Applied Economics, 2014
Soil and water conservation practices are being promoted in Ghana as a way of sustainably managing the environment to support agricultural production. Despite the important role the adoption of the practices plays in conserving the environment, very few ...

Antibiotic Resistances in Livestock: A Comparative Approach to Identify an Appropriate Regression Model for Count Data

open access: yesFrontiers in Veterinary Science, 2017
Antimicrobial resistance in livestock is a matter of general concern. To develop hygiene measures and methods for resistance prevention and control, epidemiological studies on a population level are needed to detect factors associated with antimicrobial ...

A Flexible Mixed Model for Clustered Count Data

open access: yesStats, 2022
Clustered count data are commonly modeled using Poisson regression with random effects to account for the correlation induced by clustering. The Poisson mixed model allows for overdispersion via the nature of the within-cluster correlation, however ...

Poverty and malaria morbidity in the Jirapa District of Ghana: A count regression approach

open access: yesCogent Economics & Finance, 2017
Malaria potentially affects everyone in the tropics and sub-tropics, however, the poor and vulnerable are worse affected mainly due to the socio-economic constraints that confront them. In Ghana, the Upper West Region, which is the poorest, is one of the

A Conway–Maxwell–Poisson Type Generalization of Hypergeometric Distribution

open access: yesMathematics, 2023
The hypergeometric distribution has gained its importance in practice as it pertains to sampling without replacement from a finite population. It has been used to estimate the population size of rare species in ecology, discrete failure rate in ...

On Underdispersed Count Kernels for Smoothing Probability Mass Functions

open access: yesStats, 2023
Only a few count smoothers are available for the widespread use of discrete associated kernel estimators, and their constructions lack systematic approaches. This paper proposes the mean dispersion technique for building count kernels.

A New Conway Maxwell–Poisson Liu Regression Estimator—Method and Application

open access: yesJournal of Mathematics, 2022
Poisson regression is a popular tool for modeling count data and is applied in medical sciences, engineering and others. Real data, however, are often over or underdispersed, and we cannot apply the Poisson regression. To overcome this issue, we consider

A Transition Model for Analysis of Zero-Inflated Longitudinal Count Data Using Generalized Poisson Regression Model

open access: yesRevstat Statistical Journal, 2020
In most of the longitudinal studies, involving count responses, excess zeros are common in practice. Usually, the current response measurement in a longitudinal sequence is a function of previous outcomes.

Execution of synthetic Bayesian model average for solar energy forecasting

open access: yesIET Renewable Power Generation, 2022
Accurate photovoltaic (PV) forecasting is quite crucial in planning and in the regular operation of power system. Stochastic habit along with the high risks in PV signal uncertainty and a probabilistic forecasting model is required to address the ...
