# maximumAbsoluteError(_:)

Computes the maximum absolute error between predicted and ground truth values.

## Declaration

```swift
func maximumAbsoluteError<T>(_ annotatedPredictions: [AnnotatedPrediction<T, T>]) -> T where T : FloatingPoint
```

## Parameters

- `annotatedPredictions`: An AnnotatedPrediction object.

## Return Value

Return Value The maximum absolute error.

## Discussion

Discussion If an empty AnnotatedPrediction is supplied, the result will be NaN.
