内容提示: ZERO-INFLATED NEGATIVE BINOMIAL (ZINB) REGRESSION MODEL FOR OVER-DISPERSED COUNT DATA WITH EXCESS ZEROS AND REPEATED MEASURES, AN APPLICATION TO HUMAN MICROBIOTA SEQUENCE DATA by RUI FANG Bachelor of Medicine, North China Coal Mining Medical College, 2008 A thesis submitted to the Faculty...
However, the pervasive dropout events make single-cell count data to be zero-inflated and over-dispersed. To better characterize single-cell mRNA count data, a zero-inflated negative binomial (ZINB) model has been widely used to account for the large dispersion and the dropout events28,29. ...
Green innovation: the role of government subsidies under the system of digital finance -based on a zero-inflated negative binomial model 来自 EconPapers 喜欢 0 阅读量: 17 作者:L Feng,H Chen,Y Bilan,S Khan,W Zhan,L Hens 摘要: Green innovation is inevitable for improving the environment and ...
在此基础上,Greene将ZIP模型的思想应用到负二项分布,提出了零膨胀负二项模型(zero-inflated negative binomial, ZINB),并用BHHH方法估计模型参数的标准误差(Greene, 1994)。近年来,这些模型被广泛应用在高通量组学数据的分析。 零膨胀模型的原理是将事件发生的计数看作两个不同的过程:...
而文章中,说明的是DCA takes the count distribution(数目分布), overdispersion and sparsity of the data(过离散性和稀疏性) into account using a zero-inflated negative binomial noise model(零膨胀负二项模型,后续会对ZINB模型做进一步的介绍,因为本puppy对它很是钟爱), and nonlinear gene-gene(基因与基因之...
In addition, a generalized linear model was conducted to predict the number of news sources consumed in total by age, gender, the BFI scales, and the B-RWA-6 scale. In more detail, a zero-inflated negative binomial model (using a log-link function) was implemented for the prediction of ...
In this study, we propose a tree-based scan statistic for zero-inflated count data in a hierarchical structure. According to our simulation study, in the presence of excess zeros, our proposed tree-based scan statistic provides better performance than the existing tree-based scan statistic. The ...

Zero-inflated negative binomial model for RNA-seq data (Zinb-WaVE) Risso et al. [6] proposed an extension of the remove unwanted variation (RUV) model to use the zero-inflated negative binomial (ZINB) regression to model data with technical and biological effects. The resulting model is able...
