student (n:int) : real
n>=1. Returns a drawing from a Student distribution (also called t distribution) with
n degrees of freedom.
Note that as
n increases, the Student density approaches the normal density. Indeed, even for
n=8, the Student density is almost the same as the normal density.
Raises Student exception, if
Density functions for student distributions:
An example for this distribution has been omitted due to the fact that it is rarely found in nature. Instead, the distribution is used when doing statistical tests.
