GAMMA.INV FUNCTION formula syntax
The GAMMA.INV function in Excel is used to calculate the inverse of the gamma cumulative distribution. It has the following syntax: GAMMA.INV(probability, alpha, beta) - Probability: This is the probability value between 0 and 1 for which you want to calculate the inverse of the gamma distribution. - Alpha: This parameter represents the shape parameter of the gamma distribution. It must be greater than 0. - Beta: This parameter represents the scale parameter of the gamma distribution. It must be greater than 0. The GAMMA.INV function returns the value x for which the cumulative gamma distribution is equal to the given probability.
