As a rule of thumb, if n≥100 and np≤10, the Poisson distribution (taking λ=np) can provide a very good approximation to the binomial distribution.

It is important to keep in mind that the Poisson approximation to the binomial distribution works well only when \(n\) is large and \(p\) is small. In general, ...

For situations in which n n is large and p p is very small, the Poisson distribution can be used to approximate the binomial distribution.

15 янв. 2021 г. · The short answer is that the Poisson approximation is faster and easier to compute and reason about, and among other things tells you approximately how big the ... Approximation of binomial distribution - Poisson vs Normal ... Binomial to Poisson Approximation : Why does p have to be small Другие результаты с сайта math.stackexchange.com

Clearly the Poisson is an excellent approximation when p is small. The Poisson inherits several properties from the Binomial. For example, the Bin(n, p) has ...

The Poisson distribution may be viewed as a special form of the binomial distribution and it is not surprising, therefore, that it can be used as an ...

We can use the Poisson distribution to very closely approximate the binomial distribution provided that the product [maths rendering] is constant with [maths ...

The general rule of thumb that is “taught” is that one needs both np > 10 and n(1 − p) > 10 in order for the normal approximation to be good. If the normal ...
