# `Sidereon.Estimation.AlphaBetaStep`
[🔗](https://github.com/neilberkman/sidereon-ex/blob/main/lib/sidereon/estimation.ex#L29)

Result of one alpha-beta predict and update step.

`:predicted` is the prior projected by `dt`, `:updated` is the posterior after
the measurement, and `:innovation` is `measurement - predicted.level`.

# `t`

```elixir
@type t() :: %Sidereon.Estimation.AlphaBetaStep{
  innovation: float(),
  predicted: Sidereon.Estimation.AlphaBetaState.t(),
  updated: Sidereon.Estimation.AlphaBetaState.t()
}
```
