uPoisson cumulative density
Poisson cumulative density calculates a cumulative probability at specified value
for the discrete Poisson distribution with the specified mean.
Perform the following key operations from the statistical data list.
5(DIST)
6(g)
1(POISN)
2(Pcd)
The following shows the meaning of each item when data is specified using list
specification.
Data ................ data type
List .................. list whose contents you want to use as sample data
µ
..................... mean (
µ
> 0)
Execute .......... executes a calculation
The following shows the meaning of a parameter data specification item that is
different from list data specification.
x ..................... value
Example To calculate Poisson cumulative probability for one list of data
For this example, we will calculate Poisson cumulative
probability for data = {2, 3, 4} when
µ
= 6.
