# helena-balabin-youden-index

> Metric `helena-balabin/youden_index` from the HuggingFace `evaluate` library.

## When to invoke

User asks to compute `helena-balabin/youden_index` or wants HF evaluate's canonical version.

## Recipe

```python
import evaluate
metric = evaluate.load("helena-balabin/youden_index")
result = metric.compute(predictions=preds, references=refs)
print(result)
```

## Don'ts

- Don't assume your in-house `helena-balabin/youden_index` matches HF — version conventions vary.
- Many evaluate metrics have task-specific arguments (`average=`, `lang=`, `model_type=`); read the metric card before reporting numbers.
