Webthe Clopper & Pearson (1934) approach suffers from the oppositeproblemtothatofthe‘normalapproximation’— namely, a systematic over-estimation of the CI width required to provide the desired coverage (Clopper & Pearson 1934; Neyman 1935; Gehrels 1986; Agresti & Coull 1998). In scientific research this over-estimation of WebThe Wald, Wilson Score, and Clopper-Pearson methods of calculating CI’s all assume that the variable of interest (the number of successes) can be modeled as a Binomial random variable. The difference between the first two methods can be seen most easily by examining the difference in the derivations4,5.

"WebJul 6, 2024 · Accuracy is not a single binomial proportion, so the Clopper-Pearson interval does not apply. In contrast to Normal and Poisson, the sum of two binomial random variables with different means is not (in general) a binomial. You can use a confidence interval based on the Normal approximation, preferably after some transformation like logit. " - Clopper pearson python
