Noncentral t Distribution

Evaluate and generate random samples from noncentral t distribution

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

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

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

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

  • Noncentral t Distribution

    The noncentral t distribution is a more general case of Student’s t distribution, used to calculate the power of the t test.
