MovingAverage and MovingMedian have been added to the built‐in Mathematica kernel.
ExponentialSmoothing is replaced by ExponentialMovingAverage.
MovingAverage and MovingMedian are now part of the built-in Mathematica kernel:
MovingAverage also computes weighted moving averages:
ExponentialMovingAverage replaces ExponentialSmoothing:
LinearFilter was available in previous versions of Mathematica and is now available on the web at library.wolfram.com/infocenter/MathSource/6784.
