BETAINV (percentiles of the beta distribution)

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:

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.
