PoissonGenerator
Creates a generator of Poisson-distributed values. The mean is determined by the provided
NumberGenerator. This means that the statistical parameters of this generator may change over time. One example of where this is useful is if the mean generator is attached to a GUI control that allows a user to tweak the parameters while a program is running.To create a Poisson generator with a constant mean, use the
PoissonGenerator(double, Random)constructor instead.- Parameters:
mean- ANumberGeneratorthat provides the mean of the Poisson distribution used for the next generated value.rng- The source of randomness.
