---|---|
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
