# LinearTimeSeriesForecaster

A time-series forecasting estimator.

## Declaration

```swift
struct LinearTimeSeriesForecaster<Scalar> where Scalar : MLShapedArrayScalar, Scalar : BinaryFloatingPoint
```

## Overview

Overview note: Only Float and Double are currently supported as the Scalar type. You may get faster training when using Float.
