Poisson Approximation for the Binomial Distribution • For Binomial Distribution with … Approximation via the Poisson Distribution. Poisson probability calculator with examples. It relies on the Poisson Distribution to calculate these probabilities, but uses 2 distinct methods. The symbol for this average is $ \lambda $, the greek letter lambda. Derivation of the Poisson Function from the Binomial (by William L. Hays) "Although Poisson variables and the processes generating them can be given a variety of useful interpretations, perhaps the simplest approach to the study of the Poisson is to regard it as a special case of the binomial.
