The Poisson distribution gives the probability of a certain integer number of unit rate Poisson random events occurring in a given time interval. The Poisson distribution represents an approximation to the binomial distribution for the special case where the average number of events is very much smaller than the possible number. The function poissonPF() returns the probability that a Poisson random event with Poisson mean m will occur, given n observations:
