This function returns the inverse of the gamma cumulative distribution.

GAMMAINV(p,alpha,beta)

This function has these arguments:

Argument	Description
p	Probability
alpha	Alpha parameter of the distribution
beta	Beta parameter of the distribution

This function calculates the inverse of the F probability distribution, so if p = GAMMADIST(x,...), then GAMMAINV(p,...) = x.

Accepts numeric data for all arguments. Returns numeric data.

GAMMAINV(A3,3,4)

GAMMAINV(0.8902,R3C8,R3C9)

GAMMAINV(0.75,2,3) gives the result 8.0779035867

This function is available in product version 1.0 or later.
