BETAINV

This function calculates the inverse of the cumulative beta distribution function.

Syntax

BETAINV(prob,alpha,beta,lower,upper)

Arguments

This function has these arguments:

Argument	Description
prob	Probability of the distribution
alpha	Alpha parameter of the distribution
beta	Beta parameter of the distribution
lower	[Optional] Lower bound of the interval for x; 0 if omitted
upper	[Optional] Upper bound of the interval for x; 1 if omitted

Remarks

If you omit values for upper and lower, the calculation uses the standard cumulative beta distribution, so that lower is zero and upper is one.

Data Types

Accepts numeric data for all arguments. Returns numeric data.

Examples

BETAINV(0.75,B3,C3,2,4)

BETAINV(0.75,R3C2,R3C3,2,4)

BETAINV(0.75,9,12,2,4) gives the result 3.0011968805
