Given a sequence , an -moving average is a new sequence defined from the by taking the arithmetic mean of subsequences of terms,
(1) |
So the sequences giving -moving averages are
(2) |
|||
(3) |
and so on. The plot above shows the 2- (red), 4- (yellow), 6- (green), and 8- (blue) moving averages for a set of 100 data points.
Moving averages are implemented in the Wolfram Language as MovingAverage[data, n].
