Inverse Geometric Cumulative Distribution

Menu:

[Inv. Distribution]-[Inverse Geo CD]

Description: This command calculates the inverse of the geometric cumulative

distribution.

This command returns the minimum value (positive integer) of m (

3 upper

bound) that satisfies the inequality formula above.

Calculation Result Output

x

Inv : inverse geometric cumulative distribution

*

x

Inv : recalculation value (Displayed only when there may be a possibility of

rounding error.)

• To account for possible rounding error, ClassPad additionally obtains the
result using the probability that is next lowest for the least significant digit.
For example, if the probability is 0.875, ClassPad would recalculate using 0.874.
The recalculation result is only shown if it is different from the original one.
