Set Analysis with calculation

gouthamkk — Sat, 30 Jul 2016 01:58:49 GMT

Hi,

I am trying to achieve some thing like

stdev(IF abs(val - Valmedian) < ( Valmedian*10), val)

i am trying to create a set expression where i can do median of the val which are less than 10% of total median

Valmedian - is total median without any selection and

Val - is actual value.

Something like a ZScore.

Can any one please advise.

More Explanation required, Your Expression is bit Difficult, Can i know what you want to Achieve?

Try if this works, because you can only compare dimensions with variables in set analysis

create a variable

vEval = IF(abs(val - Valmedian) < ( Valmedian*10), val)

in your chart use : STDEV($(vEval))

HI,

I wanted to calculated standard Deviation of all employee val's . who is less than median of 10% of all employees

val is a numeric value of each employee. In above case the vEval stores only single value. but i want all vEval who is less than 10% median.

Th variable will aggregate for each dimension, try it in your chart first
