GAMMA.INV
Category: Statistical Function.
Description: Returns the inverse of the gamma cumulative distribution.
If p = GAMMA.DIST(x,...), then GAMMA.INV(p,...) = x.
You can use this function to study a variable whose distribution may be skewed.
Syntax: GAMMA.INV(probability,alpha,beta)
GAMMA.INV function syntax has the following arguments:
Probability: Required. The probability associated with the gamma distribution.
Alpha: Required. A parameter to the distribution.
Beta: Required. A parameter to the distribution. If beta = 1, GAMMA.INV returns the standard gamma distribution.
