Syntax:
GAMMA.INV(Probability, Alpha, Beta)
Description:
This returns the percentiles of the gamma distribution.
Probability is the given probability from the gamma distribution. The values must be within 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 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.
Additional info:
GAMMA.INV is the inverse function of GAMMA.DIST
