This module defines random streams of events, which are useful for describing the input of the model.

- randomStream :: Parameter Double -> Stream Arrival
- randomUniformStream :: Double -> Double -> Stream Arrival
- randomNormalStream :: Double -> Double -> Stream Arrival
- randomExponentialStream :: Double -> Stream Arrival
- randomErlangStream :: Double -> Int -> Stream Arrival
- randomPoissonStream :: Double -> Stream Arrival
- randomBinomialStream :: Double -> Int -> Stream Arrival

# Stream of Random Events

randomStream :: Parameter Double -> Stream Arrival Source

Return a sream of random events that arrive with the specified delay.

Create a new stream with delays distributed uniformly.

Create a new stream with delays distributed normally.

randomExponentialStream Source

Return a new stream with delays distibuted exponentially with the specified mean (the reciprocal of the rate).

:: Double | the scale (the reciprocal of the rate) |

-> Int | the shape |

-> Stream Arrival | the stream of random events |

Return a new stream with delays having the Erlang distribution with the specified scale (the reciprocal of the rate) and shape parameters.

Return a new stream with delays having the Poisson distribution with the specified mean.
