# PreprocessingTemporalEstimator

A temporal estimator that composes a preprocessing transformer and a temporal estimator.

## Declaration

```swift
struct PreprocessingTemporalEstimator<Preprocessor, Estimator> where Preprocessor : TemporalTransformer, Estimator : TemporalEstimator, Preprocessor.Output == Estimator.Transformer.Input
```
