des-slower

Input Stack: expr: TimeSeriesExpr

⇨

Output Stack: TimeSeriesExpr

Apply double exponential smoothing using parameters optimized for very slow adaptation to changes in the input data. This provides stable smoothing with minimal sensitivity to noise.

Parameters

• expr: The time series expression to apply very slow DES smoothing to
