Note: BETAINV is supplemented by the new identical function BETA.INV, which is available in newer versions of Microsoft Excel (2010 or later).
Syntax:
BETAINV(Probability, Alpha, Beta [, A, B])
Description:
Returns the inverse of the beta distribution function (i.e., percentiles of this distribution).
Probability is the probability to be evaluated. 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) are the lower and upper bound to 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 iterative search technique. If PlanMaker does not find a result after 100 iterations that deviates less than ±3x10^-7 from Probability, it displays the error value #N/A and aborts the approximation.
