Answer by Richard Willey on 9 Jan 2012 Hi Michael MATLAB doesn't provide a specific function to remove outliers. In general you have a couple different options to deal with outliers. 1. You can create an index that flags potential outliers and either…

这篇文章更多的是对于混乱的中文资源的梳理,并补充了一些没有提到的重要参数,希望大家不会踩坑. 1. 简介 1.1 背景 WGCNA(weighted gene co-expression network analysis,权重基因共表达网络分析)是一种分析多个样本基因表达模式的分析方法,可将表达模式相似的基因进行聚类,并分析模块与特定性状或表型之间的关联关系,因此在基因组研究中被广泛应用. 相比于只关注差异表达的基因,WGCNA利用数千或近万个变化最大的基因或全部基因的信息识别感兴趣的基因集,并…
