Numeric.Probability.Object
Description
Abstract interface to probabilistic objects like random generators and probability distributions. It allows to use the same code both for computing complete distributions and for generating random values according to the distribution. The latter one is of course more efficient and may be used for approximation of the distribution by simulation.
Maybe a better name is Experiment.
