Hi, this is driving me crazy 
  i've to find correspondant function of tableau variance i QV
I'm starting from this formula
| dim | Header 2 | 
|---|---|
| A | Var(COST)/var(VALUE) | 
| B | Var(COST)/var(VALUE) | 
Who can help me, pls?
May be just square the Stdev function's result
(Stdev(COST)*Stdev(COST))/(Stdev(VALUE)*Stdev(VALUE))
May be just square the Stdev function's result
(Stdev(COST)*Stdev(COST))/(Stdev(VALUE)*Stdev(VALUE))
Or simplifying Sunny's Formula:
Pow(Stdev(COST),2) / Pow(Stdev(VALUE),2)
