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. ×tcdf: Student's t cumulative distribution, function. where x ¯ is the sample mean and s is the sample standard deviation, has Student's t distribution with n – 1 degrees of freedom. The Cauchy distribution is a Student’s t distribution with degrees of freedom ν equal to 1. The Cauchy distribution has an undefined mean and variance. where ν is the degrees of freedom and Γ(·) is the Gamma function. The result y is the probability of observing a particular value of x from a Student’s t distribution with ν degrees of freedom.. Plot. This plot shows how changing the value of the degrees of freedom parameter ν alters the shape of the pdf. Use tpdf to compute the pdf for values x equals 0 through 10, for three.

I consider, that you are not right. I can defend the position.
