Important!
When executing the Inverse Binomial Cumulative Distribution calculation, the calculator uses
the specified Area value and the value that is one less than the Area value minimum number
of significant digits (>Area value) to calculate minimum number of trials values.
The results are assigned to system variables
xInv (calculation result using Area) and >xInv
(calculation result using >Area). The calculator always displays the xInv value only. However,
when the
xInv and >xInv values are different, the message shown below will appear with both
values.
The calculation results of Inverse Binomial Cumulative Distribution 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.
I Poisson Distribution
• Poisson Probability (DIST)(E)(POISN)(PPd)
Poisson Probability calculates a probability at a specific
single
x-value or each list element for the discrete Poisson
distribution with the specified mean.
Calculation Result Output Examples
When a list is specified When variable (
x) is specified
• There is no graphing for Poisson Probability.
• Poisson Cumulative Distribution (DIST)(E)(POISN)(PCd)
Poisson Cumulative Distribution calculates the cumulative
probability in a Poisson distribution that the success will
occur on or before a specified trial.
