valuepoissonCI :: CL Double -> Int -> Estimate ConfInt Double

Calculate confidence intervals for Poisson-distributed value for single measurement. These are exact confidence intervals

valuepoissonNormalCI :: Int -> Estimate NormalErr Double

Calculate confidence intervals for Poisson-distributed value using normal approximation

valuebinomialCI

:: CL Double
-> Int
Number of trials
-> Int
Number of successes
-> Estimate ConfInt Double

Clopper-Pearson confidence interval also known as exact confidence intervals.

valuenaiveBinomialCI

:: Int
Number of trials
-> Int
Number of successes
-> Estimate NormalErr Double

Calculate confidence interval using normal approximation. Note that this approximation breaks down when p is either close to 0 or to 1. In particular if np < 5 or 1 - np < 5 this approximation shouldn't be used.
