Calculation of confidence intervals
Documentation
poissonCI :: CL Double -> Int -> Estimate ConfInt Double Source #
Calculate confidence intervals for Poisson-distributed value for single measurement. These are exact confidence intervals
poissonNormalCI :: Int -> Estimate NormalErr Double Source #
Calculate confidence intervals for Poisson-distributed value using normal approximation
Clopper-Pearson confidence interval also known as exact confidence intervals.
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.
