Probability generating function poisson
The Poisson distribution can be derived as a limiting case to the binomial distribution as the number of trials goes to infinity and the expected number of successes remains fixed — see law of rare events below. Therefore, it can be used as an approximation of the binomial distribution if n is sufficiently large and p is sufficiently small. The Poisson distribution is a good approximation of the binomial distribution if n is at least 20 and p is smaller than or equal to 0.05, and an excellen… Webb23 apr. 2024 · The probability generating function P of N is defined by P(t) = E(tN) for all t ∈ R for which the expected value exists in R. That is, P(t) is defined when E( t N) < ∞. …
