did Excel GAMMADIST parameters change??
 

In the literature, Milesky, Tucker, et.al. they use GAMMADIST with parameters
of (alpha,beta,x,cum). However my Excel has the parameters of
(x,alpha,beta,cum). Did GAMMADIST change? merely shifting "x" to the
implied new order does NOT provide the same results!
