## Methods

<a id="method-predict"></a>

### `predict`

```rust
fn predict<M: RawColumns<f64> + ?Sized>(
    &self,
    design: &M
) -> Result<Vec<f64>, FitError>
```

[Source](<https://github.com/jolars/shrinkage/blob/eeafe449edce19d3c552a03060f681ae3891af74/src/cross_validation.rs>)

Predict original-scale linear predictors from raw held-out columns. 

<a id="method-predict-documentation-errors"></a>

#### Errors

Reject invalid dimensions, entries, or prediction arithmetic. 

<a id="method-termination"></a>

### `termination`

```rust
fn termination(&self) -> Termination
```
