**'cern.jet.random.StudentT'**Java class

cern.jet.random

## Class StudentT

- All Implemented Interfaces:
- DoubleFunction, IntFunction, Serializable, Cloneable

public class StudentTextends AbstractContinousDistribution

StudentT distribution (aka T-distribution); See the math definition and animated definition.`p(x) = k * (1+x^2/f) ^ -(f+1)/2`where`k = g((f+1)/2) / (sqrt(pi*f) * g(f/2))`and`g(a)`being the gamma function and`f`being the degrees of freedom.Valid parameter ranges:

`freedom > 0`.Instance methods operate on a user supplied uniform random number generator; they are unsynchronized.

- Static methods operate on a default uniform random number generator; they are synchronized.
**Implementation:**- Method: Adapted Polar Box-Muller transformation.
- This is a port of RandStudentT used in CLHEP 1.4.0 (C++). CLHEP's implementation, in turn, is based on
`tpol.c`from the C-RAND / WIN-RAND library. C-RAND's implementation, in turn, is based uponR.W. Bailey (1994): Polar generation of random variates with the t-distribution, Mathematics of Computation 62, 779-781.
