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...

A log transformation is not always essential to analyzing the data. It can depend on the statistical analysis we are performing. If we are looking for outliers in our data, then a process that de-emphasizes them is not useful. If we use the transformation correctly, then we can illuminate ...
In this article we focus on the log-transformation and discuss major problems of using this method in prac ce. We use examples and simulated data to show that this method often does not resolve the original problem for which it is being used (i.e., non-normal ...

The level of divergence between species represented by sequence data is a function of unknown time and mutation rates. Therefore, sequence data do not reveal exact timing of evolutionary events, and inferred phylogenies often have branch lengths estimated in the unit of the expected number of ...
The log transformation has been widely used in biomedical research to deal with the skewed data. However, in the medical publications, we have found many misuses and misinterpretations of analysis based on log-transformed data. In this paper, we list some common scenarios of misuse and misinterp...
For a range of economic variables, substantial forecasting improvements from taking logs are found if the log transformation actually stabilizes the variance of the underlying series. Using logs can be damaging for the forecast precision if a stable variance is not achieved. 展开 ...
