stdevif() (aggregation function)
Calculates the stdev of Expr across the group for which Predicate evaluates to
- Can be used only in context of aggregation inside summarize
- Expr: Expression that will be used for aggregation calculation.
- Predicate: predicate that if true, the Expr calculated value will be added to the standard deviation.
The standard deviation value of Expr across the group where Predicate evaluates to
range x from 1 to 100 step 1 | summarize stdevif(x, x%2 == 0)
