| nu
| nonnegative | |

| Return Type
| numeric |
| Synopsis
| This function returns a random Student's t distributed
number with average 0 and variance nu/(nu-2).
If X is a Normal(0,1) random variable and X1 is a Chi-square
random variable with parameter nu, X/sqrt(X1/nu) is Student(nu)
distributed.
Student_Rand uses Rand() which can be seeded by either the
function SetRand or SetRandSeed. |
