PoissonDist() returns the accumulated probability of the Poisson distribution.
Syntax:
PoissonDist(value, mean)
Return data type: number
| Argument | Description |
|---|---|
| value | The value at which you want to evaluate the distribution. The value must not be negative. |
| mean | A positive number defining the average outcome. |
This function is related
to the PoissonInv function in the following way:
If prob = PoissonDist(value, mean), then PoissonInv(prob, mean) = value
