Rare-Event Analysis
Detecting populations at 1 in 10,000 or below requires collecting enough total events that the positive count is statistically stable, since the coefficient of variation of a count falls as one over the square root of that count. Roughly 100 events in the gate gives about 10 percent precision, which sets the acquisition target before the experiment starts.
