4 Zero-inflated Negative Binomial 为ZINB的概率质量函数 其中 为Dirac function, 可以视为真实的基因表达值被观测为0的概率。至此,整个ZINB模型被完整的建立起来。除了以上这种利用Poisson和Gamma mixture构造NB的方法外,也有人通过NB的两个参数mean 和inverse dispersion parameter 构造NB,即 5 Zero-inflated? (UMI ...

Zero-inflated models are useful for analyzing such data. Moreover, the non-zero observations may be over-dispersed in relation to the Poisson distribution, biasing parameter estimates and underestimating standard errors. In such a circumstance, a zero-inflated negative binomial (ZINB) model better ...
zero-inflated negative binomial distributionIn this paper, we propose 3 new sampling plans, including resubmitted single sampling plan (RSSP), repetitive group sampling (RGS) plan, and multiple dependent state (MDS) sampling plan to study the zero-inflated negative binomial distribution in ...
今天我们来将一个数据分布的情况,接触10X单细胞或者10X空间转录组不久之后,就认识到了一些数据的特征,比如经常提到的dropout/missing data/zero-inflated,当时深以为然,也没有过多思考,直觉上感觉是对的,但是随着分析的深入,很多分析点和数据分布的特点格格不入,所以最近看了几篇文献,纠正自己看法的同时,也给大家一...
In this article, the zero-inflated non-central negative binomial(ZINNB) distribution is introduced. Some of its basic properties are obtained. In addition, we use the maximum likelihood estimation method to estimate the parameters of the ZINNB distribution, and illustrate its application by fitting...
A new zero inflated distribution is proposed in this work, namely the zero inflated negative binomial-Sushila distribution. The new distribution which is a mixture of the Bernoulli and negative binomial-Sushila distributions is an alternative distribution for the excessive zero counts and over-dispersi...
