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.
