EXPONENTIALSMOOTHING(Array, DampingFactor, ShowChart, ShowStandardErrorOptions, NewTableFlag)
- where, is the input array or reference to the cells containing array,
- is a corrective factor that minimizes the instability of data,
- is a logical value that decides whether to display a chart,
- is a logical value that decides whether to calculate standard errors,
- is a logical value that decides whether to display the output in the same worksheet or a new space cube.
- EXPONENTIALSMOOTHING(), Smooths data, weighting more recent data heavier.
Description
EXPONENTIALSMOOTHING(Array, DampingFactor, ShowChart, ShowStandardErrorOptions, NewTableFlag)
- Exponential Smoothing is a technique that can be applied to a set of data, either to produce smoothed data for presentations, or to make forecasts.
- should be array of numbers.
- is the exponential smoothing constant referred as α. Value of α should be greater than '0'.
- If < 0, Calci displays #NULL error message.
- Smaller the damping factor, more smoother are the projections.
- If is omitted, Calci assumes it to be '0.3'.
- can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be FALSE.
- can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be FALSE.
- can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be FALSE.
- If is TRUE, the result is displayed on new zspace sheet.
ZOS
- The syntax is to use this function in ZOS is
- For e.g.,EXPONENTIALSMOOTHING([10,12.3,18,9.4,22,39,45,51,29],0.5,true,false,true)
Examples
Consider the following table with Columns A as data point and Column B as array input for EXPONENTIALSMOOTHING() function.
Period | Array Input | |
0 | 0 | |
1 | 45.5 | |
2 | 60 | |
3 | 200 | |
4 | 160 | |
5 | 300 | |
6 | 340 | |
7 | 310 | |
8 | 500 | |
9 | 566 | |
10 | 610 |
=EXPONENTIALSMOOTHING(B3:B13, 0.2, TRUE, FALSE, TRUE) returns the below table followed by the chart output:
Input | Output |
---|---|
0 | null |
45.5 | 0 |
60 | 36.4 |
200 | 55.28 |
160 | 171.056 |
300 | 162.21120000000002 |
340 | 272.44224 |
310 | 326.488448 |
500 | 313.2976896 |
566 | 462.65953792 |
610 | 545.331907584 |
