The passage around this formula
That combinatorial form is the unbiased estimator: it uses every one of the n observed outcomes rather than discarding some of them, and it has materially lower variance than the intuitive shortcut of raising a single measured success rate to a power. The paper is explicit that the naive alternative is biased, not merely noisier, so the difference is not a technicality —…
