Noncentral F Distribution

Evaluate and generate random samples from noncentral F distribution

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

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

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

To learn about the noncentral F distribution, see Noncentral F Distribution.

  • Noncentral F Distribution

    The noncentral F distribution is a more general case of the F distribution, used to calculate the power of a hypothesis test relative to a particular alternative.
