Documentation/How Tos/Calc: GAMMAINV function
From Apache OpenOffice Wiki
Calculates the inverse of the cumulative GAMMADIST function.
GAMMAINV(p; α; λ)
- The gamma distribution is a family of continuous probability distributions, with two controlling parameters α and λ.
- GAMMAINV returns the value n, such that GAMMADIST(n; α; λ; 1) is p.
GAMMAINV(0.86; 1; 1)
- returns approximately 2.
