I'm trying to calculate the Confidence Interval (CI) for binomial proportion. The point estimate of the proportion is 100%.
I first used the Bootstrapping and got a CI of [100%, 100%]. I was told it is not recommended to use bootstrapping CI in this case, and it's better to use the traditional method such as Wilson score CI. Using Wilson score method, I got a CI of [89%, 100%].
I'm wondering why Bootstrapping is not recommended if the observed proportion is too close to 100% and 0%? And when Bootstrapping is more preferred compared to traditional CI methods?
Thanks in advance.
