Webb2 apr. 2024 · When the Poisson is used to approximate the binomial, we use the binomial mean μ = n p. The variance of X is σ 2 = μ and the standard deviation is σ = μ. The Poisson approximation to a binomial distribution was commonly used in the days before technology made both values very easy to calculate. Example 4.7. 7.
