I've seen references to "polymars", an R implementation of Friedman's MARS algorithm. Can anyone tell me where I might be able to find this (doesn't seem to be in the contributed packages.

Dear all, I have a question on how to set up the starting model in POLYCLASS and make sure the terms in the starting model retained in the final POLYCLASS model. In the function POLYMARS, this can be done using the STARTMODEL option. See below for example, I started with model y= b0 + b1*X1 + b2*X2 + b3*X4 + b4*X5 + b5*X2*X5 + e > m00 <- matrix(c( 1, NA, 0, NA, 1, 2,

Hi there, I have a statistics question on a classification problem: Suppose I have 1000 binary variables and one binary dependent variable. I want to find a way similar to PCA, in which I can find a couple of combinations of those variables to discriminate best according to the dependent variable. It is not only for dimension reduction, but more important, for finding best way to construct

Does the polymars library exist anymore? I see reference to it at http://rweb.stat.umn.edu/R/doc/html/packages.html, but not on CRAN (looked in contrib and contrib/Old). -- Rob Schick Ecologist NOAA Fisheries Santa Cruz Lab 110 Shaffer Road Santa Cruz, CA 95060 Phone: 831.420.3960 -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Hi, I am working on a modeling project for PMI-Australia and interested in using R, especially POLYMARS or PLYCLASS. I use SAS /PC on WINDOWS for the statistical analyses including Modeling. I got R downloaded to the system but can't figure out how to interface with SAS so that I could use SAS datasets already in place. Also I could not find POLYMARS on the library packages. I need to know
