Software

(Feb 28, 2009) It is discovered that there is a subtle bug in our original code. A quick fix is available here, which can be used with the "initial R code" provided below: simply use the new "pga" function rather than the old one. Fixes to the "R package" will become available soon in the next release.

R package, version 0.1-1. R package

Initial R code (design and syntax somewhat different from the R package above).
