Description

The log normal distribution. This is a continuous probability distribution that describes data whose log is clustered around a mean. For example, the multiplicative product of many independent positive random variables.

Synopsis

data LognormalDistribution
lognormalDistr :: Double -> Double -> LognormalDistribution
lognormalDistrErr :: Double -> Double -> Either String LognormalDistribution
lognormalDistrMeanStddevErr :: Double -> Double -> Either String LognormalDistribution
lognormalStandard :: LognormalDistribution
