Article¶
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.

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:
