series_stats_dynamic()

Returns statistics for a series in a dynamic object.

The series_stats_dynamic() function takes a column containing dynamic numerical array as input and generates a dynamic value with the following content:

• min: minimum value in the input array
• min_idx: first position of the minimum value in the input array
• max: maximum value in the input array
• max_idx: first position of the maximum value in the input array
• avg: average value of the input array
• variance: sample variance of input array
• stdev: sample standard deviation of the input array
• sum: sum of the values in the input array
• len: length of the input array

Syntax

series_stats_dynamic(x [,ignore_nonfinite])

Arguments

• x: Dynamic array cell which is an array of numeric values.
• ignore_nonfinite: Boolean (optional, default: false) flag that specifies whether to calculate the statistics while ignoring non-finite values (null, NaN, inf, etc.). If set to false the returned result is null if non-finite values are present in the array.

Example

print x=dynamic([23,46,23,87,4,8,3,75,2,56,13,75,32,16,29]) 
| project stats=series_stats_dynamic(x)
