Calculation Result Output Examples
When a list is specified When variable (
x) is specified
• There is no graphing for Poisson Cumulative Distribution.
• Inverse Poisson Cumulative Distribution (DIST)(E)(POISN)(InvP)
Inverse Poisson Cumulative Distribution calculates
the minimum number of trials of a Poisson cumulative
probability distribution for specified values.

Important!
When executing the Inverse Poisson 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 will appear with both values.
The calculation results of Inverse Poisson 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 Geometric Distribution
• Geometric Probability (DIST)(E)(GEO)(GPd)
Geometric Probability calculates the probability at a specific
single
x-value or each list element, and the number of the
trial on which the first success occurs, for the geometric
distribution with a specified probability of success.
