Description:

THIS VERSION DISCONTINUED, see "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.

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

Changes to previous version:

See the alternative MLOSS entry "libstb". Updated to 1.4!

I rebuilt all the interfaces and moved some of the tricks from the earlier system into the new code. Thus the tables rebuild automatically as needed, and a float version can also be used.
