Description

Calculation of confidence intervals

Synopsis

- poissonCI :: CL Double -> Int -> Estimate ConfInt Double
- poissonNormalCI :: Int -> Estimate NormalErr Double
- binomialCI :: CL Double -> Int -> Int -> Estimate ConfInt Double
- naiveBinomialCI :: Int -> Int -> Estimate NormalErr Double

# Documentation

poissonCI :: CL Double -> Int -> Estimate ConfInt Double #

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

poissonNormalCI :: Int -> Estimate NormalErr Double #

Calculate confidence intervals for Poisson-distributed value using normal approximation

binomialCI #

Arguments

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

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

naiveBinomialCI #

Arguments

:: 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.
