Abstract
The ‘exact’ interval due to Clopper & Pearson is often considered to be the gold standard for estimating the binomial parameter. However, for practical purposes it is also often considered to be too conservative, when mean rather than minimum coverage close to nominal could be more appropriate. It is argued that (1) in their article, Clopper & Pearson themselves changed between these two criteria, and (2) ‘approximate’ is indeed better than ‘exact’.
