Description

The exponential distribution. This is the continuous probability distribution of the times between events in a Poisson process, in which events occur continuously and independently at a constant average rate.

Synopsis

- data ExponentialDistribution
- exponential :: Double -> ExponentialDistribution
- exponentialE :: Double -> Maybe ExponentialDistribution
- edLambda :: ExponentialDistribution -> Double
