    BETAINV
    In This Topic

    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
