Inverse Binomial Cumulative Distribution

Menu: [Distribution]-[Inverse Binomial CD]

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

m

Σ

x = 0

Minimum value of the upper bound of summation which satisfies the inequality m =? (integer, 0 <m <n)

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

xInv : inverse binomial cumulative distribution

*xInv : recalculation value (Displayed only when there may be a possiblility 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.
