Computes a non-overlapping block average of a series.
BLOCKAVG(series, N, rampflag)
|
series |
- |
Any series, table, or expression resulting in a series or table. |
||||
|
N |
- |
An integer, the points per block to average as the series is processed. |
||||
|
rampflag |
- |
Optional. An integer, endpoint averaging flag.
|
A series or table, the N point block average.
W1: 1..12
W2: blockavg(W1, 2)
returns the series {1.5, 3.5, 5.5, 7.5, 9.5, 11.5}
W3: 1..12
W4: blockavg(W3, 3)
returns the series {2, 5, 8, 11}
BLOCKAVG computes the N-point non-overlapping block average of a series by decimating the standard N-point moving average. If the block size is not an integral fraction of the series length, the end points are not averaged.
See MOVAVG to compute an N-point moving average and a description of rampflag.
See BLOCKMEDIAN to compute the block median of a series.
