Google can be helpful. The 10th hit I got from "projection pursuit
regression" is http://www.scs.gmu.edu/~jgentle/csi991/03f/ppreg1024.rtf,
which gives some rough outline of the algorithm. If you want more detail,
Ripley (1996) PRNN would suffice, I believe.

This is exactly what I mean by PPDE. I was reading the paper you mention below
and I was looking for already implemented code in languages like R, Matlab or
C.
Thank you all

I don't think anyone has actually answered this. PPDE is a technical
term, defined in
Friedman, Steutzle and Schroeder (1984) Projection pursuit density
estimation. Journal of the American Statistical Association,
79(387):599-608, September 1984.
I don't know of an R implementation, but have kn
Good point

Yes, xgobi does projection pursuit. Though
I'm not so sure about 'projection pursuit density estimation'.

Luis,
If I am not mistaken, the xgobi package (which requires xgobi executable)
does interactive projection pursuit. Others can correct me if I'm wrong and
there may be other packages, as well.
