Version Published Release Notes
3.0.1

version uses gammaln instead of factorials. for numerical stability.

2.0.1

Fixed a bug associated with check of persisted variable.
2.0.0

This new version brings new improvements.
1. calls to 3 factorial functions are replaced by a single call to nchoosek.
2. the vector v now persisted and checked to determine if it has been computed, thus preventing recalculation.
