GAMMAINV

Calculates the inverse of the cumulative GAMMADIST function.

Syntax:

GAMMAINV(p; α; β)

The gamma distribution is a family of continuous probability distributions, with two controlling parameters α and β.

GAMMAINV returns the value n, such that GAMMADIST(n; α; β; 1) is p.

Example:

GAMMAINV(0.86; 1; 1)

returns approximately 2.
