## `Logistic`

```python theme={null}
Logistic(
    scale_factors: Dict[str, float] = _Nothing.NOTHING,
)
```

Applies a logistic transformation to normalize trading metrics.

Method generated by attrs for class Logistic.

### Ancestors

* `systematica.portfolio.transformers.base.BaseTransformer`
* `abc.ABC`

### Instance variables

* `scale_factors: Dict[str, float]`: Scale factors for each metric to adjust the steepness of the logistic curve.

### Methods

#### `transform`

```python theme={null}
transform(
    self,
    metrics: Dict[str, float],
) ‑> Dict[str, float]
```

Normalizes all provided metrics using the logistic function.
