    This function returns the negative binomial distribution.




    This function has these arguments:

    Argument Description
    x An integer representing the number of failures in trials
    r An integer representing the threshold number of successes
    p Probability of success on each trial A number between 0 and 1
    cumulative A logical value that determines the form of the function. If cumulative is TRUE, this function returns the cumulative distribution function; if FALSE, it returns the probability density function


    The number of successes is fixed and the number of trials is variable. If p is less than 0 or greater than 1, the function returns the #NUM! error value. If x is less than 0 an error is returned. If r is less than 1 an error is returned.

    Data Types

    Accepts numeric data for all arguments. Returns numeric data.




    NEGBINOM.DIST(4,13,0.85,TRUE) gives the result 0.9012900017858557
