BETAINV

Calculates the inverse of the BETADIST function.

Syntax:

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.

Example:

BETAINV(0.96; 3; 4)

returns approximately 0.75.
