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:
Version 5.2
![<< Statistics`DataSmoothing`;
MovingAverage[{2, 5, 4, 10, 8, 6 , 10}, 3]](Files/DataSmoothing.en/legacy_1.gif)
Version 5.2
![<< Statistics`DataSmoothing`;
MovingMedian[{2, 5, 4, 10, 8, 6 , 10}, 3]](Files/DataSmoothing.en/legacy_2.gif)
MovingAverage also computes weighted moving averages:
ExponentialMovingAverage replaces ExponentialSmoothing:
Version 5.2
![<< Statistics`DataSmoothing`;
ExponentialSmoothing[{2, 5, 4, 10, 8, 6 , 10}, 1/4]](Files/DataSmoothing.en/legacy_3.gif)
LinearFilter was available in previous versions of Mathematica and is now available on the web at library.wolfram.com/infocenter/MathSource/6784.
