This function calculates the inverse of the cumulative beta distribution function.
BETAINV(prob,alpha,beta,lower,upper)
This function has these arguments:
| Argument | Description |
|---|---|
| prob | Probability of the distribution |
| alpha | Alpha parameter of the distribution |
| beta | Beta parameter of the distribution |
| lower | [Optional] Lower bound of the interval for x; 0 if omitted |
| upper | [Optional] Upper bound of the interval for x; 1 if omitted |
If you omit values for upper and lower, the calculation uses the standard cumulative beta distribution, so that lower is zero and upper is one.
Accepts numeric data for all arguments. Returns numeric data.
BETAINV(0.75,B3,C3,2,4)
BETAINV(0.75,R3C2,R3C3,2,4)
BETAINV(0.75,9,12,2,4) gives the result 3.0011968805
