u u u u u Geometric cumulative density
Geometric cumulative density calculates a cumulative probability at specified
value, the number of the trial on which the first success occurs, for the discrete
geometric distribution with the specified probability of success.
Perform the following key operations from the statistical data list.
5 (DIST)
6 (g)
2 (GEO)

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
p ..................... success probability (0 < p < 1)
Execute .......... executes a calculation
The following shows the meaning of a parameter data specification item that is
different from list data specification.
x ..................... value
• Positive integer number is calculated whether list data (Data:List) or x value
(Data:variable) is specified.
Example To calculate geometric cumulative probability for one list of
data
For this example, we will calculate geometric cumulative
probability for data = {2, 3, 4} when
p = 0.5.
