Detailed Description
This class implements Student random variate generators using the polar method of [14] .
The code is adapted from UNURAN (see [166] ).
The non-static nextDouble method generates two variates at a time and the second one is saved for the next call. A pair of variates is generated every second call. In the static case, two variates are generated per call but only the first one is returned and the second is discarded.
The documentation for this class was generated from the following file:
