Inverse Binomial Cumulative Distribution

Menu: [Inv. Distribution]-[Inverse Binomial CD]

Description: This command calculates the inverse of the binomial cumulative distribution.

Σm

x= 0

This command returns the minimum value (positive integer) of m (Σ upper bound) that satisfies the inequality formula above.

Definition of Terms

prob : binomial cumulative probability (0 < prob < 1)

Numtrial : number of trials n (integer, n > 0)

pos : probability of success p (0 < p < 1)

Calculation Result Output

inverse binomial cumulative distribution

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 0.61, ClassPad would recalculate using 0.60. The recalculation result is only shown if it is different from the original one.
