Description

MOVINGAVERAGE(Array, PeriodInterval, ShowChart, ShowStandardErrorOptions, NewTableFlag)

• Moving average is a calculation to analyze data points by creating a series of averages of different subsets of the full data set.
• $Array$ can be any positive integers including zero '0'.
• e.g. If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle PeriodInterval} 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 Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle PeriodInterval} is omitted, Calci assumes it to be 3.
• If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle PeriodInterval} < 4, Calci returns an #N/A error message.
• If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle PeriodInterval} > 'Length of Array', Calci returns an #N/A error message.
• Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle ShowChart} can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be FALSE.
• Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle ShowStandardErrorOptions} can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be FALSE.
• Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle NewTableFlag} can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be FALSE.
• If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle NewTableFlag} is TRUE, the result is displayed on new zspace sheet.

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(B3:B13, 6, TRUE, FALSE, TRUE) returns the below table followed by the chart output:

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
