# PreprocessingSupervisedTabularEstimator

A supervised tabular estimator that composes a preprocessing transformer and a supervised tabular estimator.

## Declaration

```swift
struct PreprocessingSupervisedTabularEstimator<Preprocessor, Estimator> where Preprocessor : TabularTransformer, Estimator : SupervisedTabularEstimator
```
