PoissonInv() returns the inverse of the accumulated probability of the Poisson distribution.
Syntax:
PoissonInv(prob, mean)
Return data type: number
| Argument | Description |
|---|---|
| prob | A probability associated with the Poisson-probability distribution. It must be a number between 0 and 1. |
| mean | A positive number defining the average outcome. |
This function is related
to the PoissonDIST function in the following way:
If prob = PoissonDist(value, mean), then PoissonInv(prob, mean) = value
