Hi list, I am just a new user of R. How can I run stepwise regression in R? Is there a graphic user interphase for any of the spatial packages inculded in R, such as gstat, geoR and someothers. I am mainly interested interactive variogram modelling and mapping. Thanks Mahdi -- ----------------------------------- Mahdi Osman (PhD) E-mail: m_osm at gmx.net ----------------------------------- 10 GB Mailbox, 100 FreeSMS http://www.gmx.net/de/go/topmail

If you look for a stepwise procedure for Linear Regression Models or Generalized Linear Models, you can use step() (see ?step) Regards, Christoph -------------------------------------------------------------- Christoph Buser <buser at stat.math.ethz.ch> Seminar fuer Statistik, LEO C11 ETH (Federal Inst.

also stepAIC in library(MASS). hope this helps. spencer graves Christoph Buser wrote:>Dear Mahdi > >Mahdi Osman writes: > > Hi list, > > > > I am just a new user of R. > > > > How can I run stepwise regression in R? > >If you look for a stepwise procedure for Linear Regression >Models or Generalized Linear Models, you can use step() >(see ?step) > >Regards, > >Christoph > >-------------------------------------------------------------- >Christoph Buser <buser at stat.math.ethz.ch> >Seminar fuer Statistik, LEO C11 >ETH (Federal Inst.
