Beta Distribution

Fit, evaluate, and generate random samples from beta distribution

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

  • Create a BetaDistribution object and use BetaDistribution object functions.

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

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

To learn about the beta distribution, see Beta Distribution.

  • Beta Distribution

    The beta distribution describes a family of curves that are nonzero only on the interval [0,1].
