GAMMA.INV Function Explained

The GAMMA.INV Function in Microsoft Excel calculates the inverse of the gamma cumulative distribution for a supplied probability. It takes three arguments: probability, alpha, and beta. The probability argument is a probability associated with the gamma distribution. The alpha argument is a parameter associated with the gamma distribution. The beta argument is a parameter associated with the gamma distribution. The function returns the value that corresponds to the supplied probability.
