Thank you. I want to pick the exact A that would point me to B. But I apologize, I should have labeled them A (and -A), C (and -C), D (and -D)..., because they are actually different things that happen simultaneously with B. There might be (should be, even) interdependence between them (at least most of them), so I won't use it as a very reliable indicator. Just a way to quickly estimate what I expect to see.
Are you, then, trying to find which event gives you the most information about whether or not B occurred?
I think it's past time for another Stupid Questions thread, so here we go.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Please respect people trying to fix any ignorance they might have, rather than mocking that ignorance.
