Hello, I am using projection pursuit regression parameters selection. Does anyone has experience on the range to test for df parameter (spline kernel) and gcvpen (gcvspline kernel)? I don't find any information about this. Thanks in advance. Joao Moreira [[alternative HTML version deleted]]

...om "make check" on a Linux alpha (Red Hat 6.0) using egcs-1.1.2 compiler, and compiling from R-base-0.64.1-5.src.rpm packaged by Red Hat Contrib|Net. make check fails with return code 136 from modreg-Ex.Rout. The final output is: > plot(update(rock.ppr, sm.method="gcv", gcvpen=2), + main = "update(..., sm.method=\"gcv\", gcvpen=2)") Floating point exception Is this error known? Is it associated with floating point exception handling by Linux kernel (2.2.5-16 of Red Hat distribution) on alpha hardware? Or, is it .... ? Thanks, Dick...

Dear R users, I am looking for the source code of the implementation of ppr (Projection Pursuit Regression) in R. It will be great if citations of the source papers on which the implementation is based, are also provided.
