Hi - A little while ago I posted a question about the implementation of
a two-dimensional analog of the Kolmogorov-Smirnov test in R[1][2]. As
there isn't one, as far as I know, people might be interested in a very
fast C++ implementation called MUAC which is available as a function
and as a standalone program from
http://www.acooke.org/jara/muac/index.html. Apparently the code is
interesting from a computer science viewpoint, and an MPI-powered
parallel version is available from
http://beowulf.lcs.mit.edu/18.337-2002/projects-2002/ianchan/KS2D/
Project%20Page.htm
If anyone has any experience of this code, and in particular words of
warning, I'd love to hear about them (off-list would be best).
