In this comprehensive guide, we'll explore the negative binomial distribution's mathematical foundations, practical applications, and implementation in Python and R. Starting from its basic properties and moving
之所以称其为 negative binomial distribution(负二项式分布),在于: (r+k−1k)=(r+k−1)!k!(r−1)!===(r+k−1)(r+k−2)…(r)k!(−1)k(−r)(−r−1)…(−r−k+1)k!(−1)k(−rk) 此时不妨对其能否构成概率分布进行简单验证: ∑kPr(X=k)===(1−p)r∑k(−...
Differential expression quantifiers including log2 fold change and false discovery rate (FDR) were computed using the R 3.6.0 Bioconductor package edgeR 3.26.0 [30] that implements scRNA-seq differential expression analysis methodology based on the Negative Binomial distribution. First, we applied scran...
The counts Y were then drawn from a negative binomial distribution with mean \(M=0.2+FW^{\prime}\) and shape parameter 10 to promote overdispersion. A random subset of 65 observations (5%) was withheld for validation leaving 1,231 for training. For MEFISTO, RSF and FA the count data ...

HiCzin is a normalization method designed for metagenomic Hi-C data. HiCzin is based on the zero-inflated negative binomial regression frameworks. We model the population of the intra-species contacts using the negative binomial distribution. HiCzin combines the counting distribution of the intra-spe...

Figure 1. Distribution of drift rate (v) for suicide attempters (SA) (solid lines) and suicide ideators (SI) (dashed lines) for positive (blue lines) and negative (red lines) stimuli. These results indicated that the two groups did not differ in their drift rate for positive or negative...
A Python-based toolkit, Scanpy (version 2.3.4) (Wolf et al., 2018), was used for analyzing the single-cell RNA-Seq (scRNA-seq) data. Specifically, the raw UMI matrix was processed to filter out genes detected in less than 10 cells and cells with fewer than 200 genes. We further ...
(ReLU) and the softmax activation function, as indicated. The latter normalises the network output to the probability distribution. The size of the convolutional kernels is specified in the orange boxes, the dimensions of the resulting feature maps are given in the blue boxes [pixels]. The ...
