Description:

THIS VERSION DISCONTINUED. See "libstb" at http://mloss.org/software/view/424/

This source directory contains library routines that provide alternative ways of computing generalised second order Stirling numbers used in working with Pitman-Yor and Dirichlet processes (PYP and DP). Included is library routines for posterior sampling on the discount and concentration parameters of the PYP/DP, and some simple demo scripts.

Tested on a few versions on Ubuntu Linux and MacOSX. Requires the GSL (GNU Scientific Library) for polygamma functions.

Matching paper with some of the theory at http://arxiv.org/abs/1007.0296

Changes to previous version:

Replaces "libstb 1.0" release with complete rebuild.
