    • 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
