WebJun 23, 2024 · 2. Bootstrapping is a bit unnecessary when you can get e.g. an exact Clopper-Pearson confidence interval (even trivially hand-calculated for any software that supports the Beta-distribution). Bootstrapping also does not work "so well", if you have e.g. an observed sensitivity of specificity of 100 or 0%. – Björn. WebMar 7, 2024 · Conversely, the Clopper-Pearson Exact method is very conservative and tends to produce wider intervals than necessary. Brown et al. recommends the Wilson or Jeffreys methods for small n and Agresti-Coull, Wilson, or Jeffreys, for larger n as providing more reliable coverage than the alternatives.

WebWhen we updated the software to SPC XL 2007/2010, the Binomial Confidence Interval was changed to the Exact or Clopper-Pearson method. Final Notes. The term “Exact Confidence Interval” is a bit of a misnomer. Neyman noted [4] that “exact probability statements are impossible in the case of the Binomial Distribution”. This stems from the ... Webusing three approaches: the ‘Wald’ (Normal) interval, the Wilson score interval and the ‘exact’ Clopper-Pearson Binomial interval.

"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
