Documentation/How Tos/Calc: BETAINV function
From Apache OpenOffice Wiki
Calculates the inverse of the BETADIST function.
BETAINV(p; α; β; a; b)
- The beta distribution is a family of continuous probability distributions, defined for an interval a to b, where α and β are parameters controlling the shape of the distribution.
- BETAINV returns the value n, lying between a and b, such that BETADIST(n; α; β; a; b) is p.
- a and b are optional parameters which default (if omitted) to 0 and 1.
BETAINV(0.96; 3; 4)
- returns approximately 0.75.
