    This function calculates the cumulative beta distribution function.




    This function has these arguments:

    Argument Description
    x Value at which to evaluate the function, between the values of lower and upper
    alpha Alpha parameter of the distribution
    beta Beta parameter of the distribution
    cumulative A logical value that determines the function form. The function returns the cumulative distribution function if this argument is true. It returns the probability density function, if the argument is false
    lower [Optional] Lower bound of the interval for x; 0 if omitted
    upper [Optional] Upper bound of the interval for x; 1 if omitted


    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 except cumulative. Accepts TRUE or FALSE for cumulative. Returns numeric data.



    BETA.DIST(2,8,10,TRUE,1,3) gives the result 0.6854705810546875
