Description

The normal distribution. This is a continuous probability distribution that describes data that cluster around a mean.

Synopsis

data NormalDistribution
normalDistr :: Double -> Double -> NormalDistribution
normalDistrE :: Double -> Double -> Maybe NormalDistribution
normalDistrErr :: Double -> Double -> Either String NormalDistribution
standard :: NormalDistribution

Arguments

:: Double	Mean of distribution
-> Double	Standard deviation of distribution
-> Maybe NormalDistribution

Create normal distribution from parameters.

IMPORTANT: prior to 0.10 release second parameter was variance not standard deviation.

normalDistrErr Source #

Arguments

:: Double	Mean of distribution
-> Double	Standard deviation of distribution
-> Either String NormalDistribution
