GAMMA.INV (percentiles of the gamma distribution)

Syntax:

GAMMA.INV(Probability, Alpha, Beta)

Description:

Returns the percentiles of the gamma distribution.

Probability is the probability to be evaluated. Must be in the range 0 to 1.

Alpha and Beta are shape parameters of the function. They both have to be greater than zero.

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.

Annotation:

GAMMA.INV is the inverse function of GAMMA.DIST
