Method Details
-
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
-
beta
Equivalent toalpha
, but controls the smoothing of the trend instead of the data- Parameters:
beta
- a double between 0-1 inclusive, controls trend smoothing- Returns:
- The builder to continue chaining
