WebFeb 1, 2024 · Exact CIs, aka Clopper-Pearson. For one simple example, recall the assumption that we always have to make for our Normal approximation method: \(n * \hat\pi > 5\) and \(n * (1 - \hat\pi) > 5\). This is required when we use the Normal approximation. It means we can’t build CIs for small-ish samples. But other methods don’t have this problem!
