Print summary statistics for a fitted `hfr`

model

## Usage

```
# S3 method for hfr
print(x, ...)
```

## Arguments

- x
Fitted `hfr`

model.

- ...
additional methods passed to `print`

.

## Value

Summary statistics of HFR model

## Details

The call that produced the object `x`

is printed, following by a
`data.frame`

of summary statistics, including the effective degrees of freedom
of the model, the R.squared and the regularization parameter.

## Examples

```
x = matrix(rnorm(100 * 20), 100, 20)
y = rnorm(100)
fit = hfr(x, y, kappa = 0.5)
print(fit)
#>
#> Call: hfr(x = x, y = y, kappa = 0.5)
#>
#> Df R.squared kappa
#> 1 11 0.23 0.5
