WebPoisson Random Variate Generation. Abstract : Approximate algorithms have long been the only available methods for generating Poisson random variates when the mean is large. A new algorithm is developed that is exact, has execution time insensitive to the value of the mean, and is valid whenever the mean is greater than ten. This algorithm is ...
