I need to implement variable selection procedures (such as stepwise and
backward selection) in Cox proportional hazards model, but can't seem to
find an R or S-plus command for these procedures. I am aware that these
can be done in SAS.
I would appreciate help from anyone who knows how to implement these
procedures in Cox models using S-plus or (preferably) R.
