Syntax:
BETA.INV(Probability, Alpha, Beta [, A, B])
Description:
This returns percentiles of a beta distribution.
Probability is the given probability from the beta distribution. It must be > 0 and ≤ 1.
Alpha and Beta are shape parameters of the function. They both have to be greater than zero.
A and B (optional) determine the limits of the interval. If they are omitted, A is set to 0 and B is set to 1 (thus leading to a normal distribution).
Note:
The result of this function is calculated using an iteration method. If, after 100 iterations, PlanMaker does not find a result that deviates less than ±3x10^-7 from Probability, it displays the error value #N/A and cancels the approximation.
Compatibility notes:
Microsoft Excel supports this function only in version 2010 or later. The function is unknown in older versions.
Additional info:
BETA.INV is the inverse function of BETA.DIST
