log transformation对数转换 log transformation refers to the technique of taking the logarithm of a variable in order to transform it into a more linear relationship. It is commonly used in statistical analysis and data visualization to deal with data that exhibits exponential growth or extreme ...
事实上,其实是我们对数据进行了对数转换(log transformation),也就是我们常说的取log。通常使用以10为底(log10)、以2为底(log2)和自然对数(loge)。 所以我们为什么要取对数呢?是因为我们平常得到的表达矩阵中,不同样本之间同一个基因表达差异过大,也存在不同基因在同一样本之间差异过大,都不能很好的进行可视化...
4.2.1 Distribution Data normality can influence the estimation of certain SIMs which assume that the input data are distributed normally about their mean. If this assumption is not met, log transformation is commonly applied, thus resulting in lognormal methods (e.g., lognormal kriging; Cressie,...
