# `Sidereon.Estimation.NisGate`
[🔗](https://github.com/neilberkman/sidereon-ex/blob/main/lib/sidereon/estimation.ex#L64)

Normalized innovation squared gate result.

`:nis` is the statistic, `:threshold` is the chi-square threshold for the
requested confidence and degrees of freedom, and `:in_gate` is true when
`nis <= threshold`.

# `t`

```elixir
@type t() :: %Sidereon.Estimation.NisGate{
  dof: pos_integer(),
  in_gate: boolean(),
  nis: float(),
  threshold: float()
}
```
