!probability,alpha,beta!!Returns the inverse of the gamma cumulative distribution: if p = GAMMA.DIST(x,...), then GAMMA.INV(p,...) = x!is the probability associated with the gamma distribution, a number between 0 and 1, inclusive!is a parameter to the distribution, a positive number!is a parameter to the distribution, a positive number. If beta = 1, GAMMA.INV returns the inverse of the standard gamma distribution!
