Distribution
u u u u u Poisson cumulative density
Poisson cumulative density calculates the probability of Poisson distribution data
falling between two specific values.
Perform the following key operation from the statistical data list.
The following shows the meaning of each item when data is specified using list
specification.
The following shows the meaning of parameter data specification item that is
different from list data specification.

To calculate Poisson cumulative density for one list of data
For this example, we will calculate Poisson cumulative density
for data = {2, 3, 4} when µ = 6.
