In this article, we provide an overview of negative binomial regression and outline both maximum likelihood and robust estimation. We discuss how the negative binomial model is a generalization of the Poisson and provide an example that considers recurrence of bladder cancer tumors.Wiley StatsRef: Statistics Reference Onlinedoi:10.1002/9781118445112.stat08246...
semiparametric negative binomial regressionoverdispersionThe negative binomial (NB) is frequently used to model overdispersed Poisson count data. To study the effect of a continuous covariate of interest in an NB model, a flexible procedure is used to model the covariate effect by fixed-knot cubic ...
The traditional negative binomial regression model, designated the NB2 model in [1], is (2) where the predictor variables are given, and the population regression coefficients are to be estimated. Given a random sample of subjects, we observe for subject the dependent variable and the predictor ...

• Clearly this model fits better than Poisson Regression Model. • For the negative binomial model, SD/mean is estimated to be 0.43 = sqrt(1/k). • For these 10 cells, ratios range from 0.24 to 0.67, consistent with that value. ...

由于技术因素,scRNA-seq数据可能由于每个细胞中检测到的分子数量不同导致细胞与细胞间的差异。为了解决区分生物学异质性与技术造成的差异,本文提出正则化负二项分布中的皮尔逊残差(其中细胞测序深度用作广义线性模型中的协变量)在保留生物异质性的同时成功地消除了测序深度的影响。 文章原文:https://link.springer.com/...
