des-slow

Input Stack:
expr: TimeSeriesExpr
Output Stack:
TimeSeriesExpr

Apply double exponential smoothing using parameters optimized for slow adaptation to changes in the input data. This provides stable smoothing that responds gradually to changes.

Parameters

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