This function calculates the inverse of the cumulative beta distribution function.
Syntax
BETAINV(prob,alpha,beta,lower,upper)
Arguments
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 |
Remarks
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.
Data Types
