# Student's t Distribution

Evaluate and generate random samples from Student’s t distribution

Statistics and Machine Learning Toolbox™ offers multiple ways to work with the Student’s t distribution.

• Use distribution-specific functions with specified distribution parameters. The distribution-specific functions can accept parameters of multiple Student’s t distributions.

• Use generic distribution functions (cdf, icdf, pdf, random) with a specified distribution name ('T') and parameters.

To learn about the Student's t distribution, see Student's t Distribution.

## Topics

Student's t Distribution

The Student’s t distribution is a family of curves depending on a single parameter ν (the degrees of freedom).

Generate Cauchy Random Numbers Using Student's t

This example shows how to use the Student's t distribution to generate random numbers from a standard Cauchy distribution.
