| Poisson d. |
the probability distribution that describes counts of events randomly distributed in time or space, such as radioactive decay or blood cell counts. The probability of observing exactly k events in a fixed time period or region is f(k) = λke-λk! where λ is the average density of events in a period or region of that size and e is the base of natural logarithms (2.718). The mean and variance of the distribution are both equal to λ, thus the coefficient of variation for a Poisson distribution is 1/ (the variability of the count is inversely proportional to the square root of the average count).
