Synopsis

data NormalDistribution fromParams :: Double -> Double -> NormalDistribution fromSample :: Sample -> NormalDistribution standard :: NormalDistribution

Documentation

data NormalDistribution Source

The normal distribution.

Constructors

fromParams Source

:: Double Mean of distribution -> Double Variance of distribution -> NormalDistribution Create normal distribution from parameters

fromSample :: Sample -> NormalDistribution Source

Create distribution using parameters estimated from sample. Variance is estimated using maximum likelihood method (biased estimation).

standard :: NormalDistribution Source

Standard normal distribution with mean equal to 0 and variance equal to 1
