I want to remove data that is more than average + standard deviation in load script:
These are the solutions that I tried:
if(round([Run time]-[collection Time]) <= avg(round([Run time]-[collection time])+Stdev(round([Run time]-[collection time]))),round(([Run time]-collection time])*24*60),) as AB
Load Error that I get: nested aggregation
Stdev([Run time]-[Collection time] as std,
avg([Run time]-[Collection time] ) as avg.
....Then use these 2 in my chart expression
Load Error: expression not valid
Solution 3: I was thinking to define a variable in load and use variables instead of [Run time]-[Collection time]
But I am not sure of this neither. Does any have any ideas about nested aggregation and how it can be resolved?
**I also used set analysis for this , but since I am using an expression in my set it does not show any valid chart.
