Negative Binomial Distribution

Fit parameters of the negative binomial distribution to data, evaluate the distribution or its inverse, generate pseudorandom samples

Statistics and Machine Learning Toolbox™ offers multiple ways to work with the negative binomial distribution.

  • Create a NegativeBinomialDistribution object and use NegativeBinomialDistribution object functions.

  • Use distribution-specific functions with specified distribution parameters. The functions can accept parameters of multiple negative binomial distributions.

  • Use the generic distribution functions with the specified distribution name "Negative Binomial" and corresponding parameters.

To learn about the negative binomial distribution, see Negative Binomial Distribution.

  • Negative Binomial Distribution

    The negative binomial distribution models the number of failures before a specified number of successes is reached in a series of independent, identical trials.
