SINGLEEXPONENTIALSMOOTHING is available since version 1.0.0.
SINGLEEXPONENTIALSMOOTHING function takes a Geo Time Series™ and smooths it with the
additive Simple Exponential Smoothing formula.
It consumes two parameters from the top of the stack:
- A level smoothing factor alpha (a numeric parameter between 0 < alpha < 1)
- The GTS to smooth
The resulting smoothed GTS is pushed onto the stack.
