Normalization and variance stabilization of single-cell RNA-seq data using regularized negative binomial regression [PDF]

open access: goldGenome Biology, 2019
Single-cell RNA-seq (scRNA-seq) data exhibits significant cell-to-cell variation due to technical factors, including the number of molecules detected in each cell, which can confound biological heterogeneity with technical effects.

OVERDISPERSION HANDLING IN POISSON REGRESSION MODEL BY APPLYING NEGATIVE BINOMIAL REGRESSION

open access: diamondBarekeng, 2023
Statistical analysis that can be used if the response variable is quantified data is Poisson regression, assuming that the assumption must be met equidispersion, where the average response variable is the same as the standard deviation value.

Improved estimation in negative binomial regression. [PDF]

open access: yesStat Med, 2022
AbstractNegative binomial regression is commonly employed to analyze overdispersed count data. With small to moderate sample sizes, the maximum likelihood estimator of the dispersion parameter may be subject to a significant bias, that in turn affects inference on mean parameters.

Early warning and predicting of COVID-19 using zero-inflated negative binomial regression model and negative binomial regression model [PDF]

open access: yesBMC Infectious Diseases
Background It is difficult to detect the outbreak of emergency infectious disease based on the exiting surveillance system. Here we investigate the utility of the Baidu Search Index, an indicator of how large of a keyword is in Baidu’s search volume, in ...

NIMBus: a negative binomial regression based Integrative Method for mutation Burden Analysis [PDF]

open access: goldBMC Bioinformatics, 2020
Background Identifying frequently mutated regions is a key approach to discover DNA elements influencing cancer progression. However, it is challenging to identify these burdened regions due to mutation rate heterogeneity across the genome and across ...

A Novel Phylogenetic Negative Binomial Regression Model for Count-Dependent Variables [PDF]

open access: yesBiology, 2023
Regression models are extensively used to explore the relationship between a dependent variable and its covariates. These models work well when the dependent variable is categorical and the data are supposedly independent, as is the case with generalized

NEGATIVE BINOMIAL REGRESSION AND GENERALIZED POISSON REGRESSION MODELS ON THE NUMBER OF TRAFFIC ACCIDENTS IN CENTRAL JAVA

open access: diamondBarekeng, 2022
Traffic accidents that always increase along with the increasing population growth and the number of vehicles impact the national economy. The number of traffic accidents is a count data that a Poisson distribution can approximate. The Poisson regression

Disease Mapping via Negative Binomial Regression M-quantiles [PDF]

open access: yesStatistics in Medicine, 2013
We introduce a semi-parametric approach to ecological regression for disease mapping, based on modelling the regression M-quantiles of a Negative Binomial variable. The proposed method is robust to outliers in the model covariates, including those due to

Double Generalized Beta-Binomial and Negative Binomial Regression Models

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.
