```
public interface ScalingFunction
```
Interface for scaling functions used, e.g., by outlier evaluation such as Histograms and visualization.
When using outlier scaling functions, make sure to invoke prepare to invoke the preprocessing step!
Outside of an outlier context, you probably want to use StaticScalingFunction instead, which may not require a prepare statement.
