!probability,alpha,beta!!This function is available for compatibility with Excel 2008 and earlier.Returns the inverse of the gamma cumulative distribution: if p = GAMMADIST(x,...), then GAMMAINV(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, GAMMAINV returns the inverse of the standard gamma distribution!
