Arguments

:: Double

Mean of distribution

-> Double

Standard deviation of distribution

-> NormalDistribution

Create normal distribution from parameters.

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

normalFromSample :: Sample -> NormalDistribution

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

standard :: NormalDistribution

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