The moving average functions compute average values in a series.
- CMAVG computes the cumulative moving average of a value from the beginning of a series.
- EMAVG computes the exponential moving average—the average of points in a series, exponentially decreasing the weights of older values.
- SMAVG computes the simple moving average of points in a series.
- WMAVG computes the weighted moving average—the average of points in a series, applying weights to older values. The weights for the older values decrease arithmetically.
