The calculation results of invGeoCDf are integers. Accuracy may be reduced when the
first argument has 10 or more digits. Note that even a slight difference in calculation
accuracy affects calculation results. If a warning message appears, check the displayed
values.
Example: To determine the minimum number of trials when
prob = 0.875, pos = 0.5

u hypergeoPDf
Function: Returns the probability in a hypergeometric distribution that the success will
occur on a specified trial.
Syntax: hypergeoPDf(
x, n, M, N [ ) ]
Example: Determine the hypergeometric probability when
x = 1, n = 5, M = 10, N = 20.
Menu Item: [Action][Distribution][hypergeoPDf]
For more information, see “Hypergeometric Distribution Probability” on page 7-11-23.
u hypergeoCDf
Function: Returns the cumulative probability in a hypergeometric distribution that the
success will occur between specified lower value and upper value.
Syntax: hypergeoCDf(lower value, upper value,
n, M, N [ ) ]
Example: Determine the hypergeometric cumulative distribution when lower value = 0,
upper value = 1,
n = 5, M = 10, N = 20.
Menu Item: [Action][Distribution][hypergeoCDf]
For more information, see “Hypergeometric Cumulative Distribution” on page 7-11-24.
u invHypergeoCDf
Function: Returns the minimum number of trials of a hypergeometric cumulative
distribution for specified values.
Syntax: invHypergeoCDf(
prob, n, M, N [ ) ]
Important!
When executing the invHypergeoCDf 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 invHypergeoCDf 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.
