MOVINGAVERAGE(Array, PeriodInterval, NewTableFlag)

  • where, is an array of reference to cells containing an array
  • represents the number of intervals
  • is a logical value that decides whether to display the output in the same worksheet or a new space cube.

MOVINGAVERAGE() calculates the expected value, over a past period of fixed length at any time.

Description

MOVINGAVERAGE(Array, PeriodInterval, NewTableFlag)

  • Moving average is a calculation to analyze data points by creating a series of averages of different subsets of the full data set.
  • can be any positive integers including zero '0'.
  • e.g. If is set to '6', the average of previous 5 points and the current data point is calculated. Moving Average for first '5' data points cannot be calculated due to less number of data points. Hence Moving average for first '5' data points will be null.
  • If is omitted, Calci assumes it to be 3.
  • If < 4, Calci returns an #N/A error message.
  • If > 'Length of Array', Calci returns an #N/A error message.
  • 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.

<font=blue>Need to check the functionality of NewTableFlag after next release

Examples

Consider the following table with Columns A as data point and Column B as array input for MOVINGAVERAGE() 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 
=MOVINGAVERAGE(A1:A11, 6, TRUE) returns the following table:

MOVING AVERAGE
Input Moving Average
0 null
45.5 null
60 null
200 null
160 null
300 127.58333333333333
340 184.25
310 228.33333333333334
500 301.6666666666667
566 362.6666666666667
610 437.6666666666667
