Kind people,
I just ran across this, and was wondering whether it's worth a
back-patch. The interval type has an aggregate for average (AVG), but
not one for standard deviation (STDDEV) or variance (VARIANCE).
Is this a bug? Is there some problem with defining variance over
intervals?
TIA for any pointers in the right direction...
Cheers,
D
