Variance Stabilizing Transformations
====================================
Feature-engine's variable transformers transform numerical variables with various
mathematical transformations.
Variable transformations are commonly used to spread the values of the original variables
over a wider value range. See the following illustration:

We added a lot of information about **variance stabilizing transformations** in this
`article `_.
**Note**
Note however, that improving the value spread is not always possible and it depends
on the nature of the variable.
