- Method Detail
  - alpha
```
public EwmaModel.EWMAModelBuilder alpha(double alpha)
```
    Alpha controls the smoothing of the data. Alpha = 1 retains no memory of past values (e.g. a random walk), while alpha = 0 retains infinite memory of past values (e.g. the series mean). Useful values are somewhere in between. Defaults to 0.5.
    
    Parameters:
    
    alpha - A double between 0-1 inclusive, controls data smoothing
    
    Returns:
    
    The builder to continue chaining
