## Ejemplo
|
|
|
|
```python
|
|
from geometric_mean import geometric_mean
|
|
|
|
geometric_mean([1, 2, 4, 8]) # 2.828... (= 2^1.5)
|
|
geometric_mean([1, -2, 3]) # exp((log(1)+log(3))/2) — ignores -2
|
|
geometric_mean([]) # math.nan
|
|
geometric_mean([-1, -2]) # math.nan — no positives
|
|
```

## Notas
|
|
|
|
Apropiado para distribuciones lognormales o datos multiplicativos (precios, ratios, crecimientos). Equivalente a la raiz n-esima del producto pero numericamente mas estable via log-space.
