Hi @zabetak — hope you're doing well. Just checking in on this one.
I realize my May 4 response with the GROUP BY example might have come
across as pushing a specific direction. I'm genuinely open to whichever path
you think is
best here — whether that's keeping the +1 for known-NDV columns, exploring
its removal as a separate effort, or something else entirely.
Is there any additional analysis, test case, or alternative approach I can
provide to help you evaluate this? Happy to prototype whatever would be most
useful.
Thanks for your time — I know these stats questions aren't straightforward.
