S geoPDf
Function: Returns the probability in a geometric distribution that the success will occur on
a specified trial.
Syntax: geoPDf(
x
,
pos
[ ) ]
Example: To determine the geometric probability when
x
= 6,
pos
= 0.4
Menu Item: [Action][Distribution][geoPDf]
For more information, see “Geometric Distribution Probability” on page 7-11-20.
S geoCDf
Function: Returns the cumulative probability in a geometric distribution that the success
will occur between specified lower value and upper value.
Syntax: geoCDf(lower value, upper value,
pos
[ ) ]
Example: To determine the geometric probability when lower value = 2, upper value = 3,
pos
= 0.5
Menu Item: [Action][Distribution][geoCDf]
For more information, see “Geometric Cumulative Distribution” on page 7-11-21.
S invGeoCDf
Function: Returns the minimum number of trials of a geometric cumulative probability
distribution for specified values.
Syntax: invGeoCDf(
prob
,
pos
[ ) ]
Important!
When executing the invGeoCDf function the calculator uses the specified
prob
value
and the value that is one less the
prob
value minimum number of significant digits (*
prob
value) to calculate minimum number of trials values. The results are assigned to the
system variables
xInv
(calculation result using
prob
) and *
xInv
(calculation result using
*
prob
). The invGeoCDf function always returns the
xInv
value only. However, when the
xInv
and *
xInv
values are different, the warning message shown below appears showing
both values.
