survival analysis using rpart
Hello,
I use rpart to predict survival time and have a problem in interpreting the
output of ?estimated rate?. Here is an example of what I do:
> stagec <-
> read.table("http://www.stanford.edu/class/stats202/DATA/stagec.data",
> col.names=c("pgtime", "pgstat", "age","eet", "g2", "grade", "gleason",
> "ploidy"))
> fit <- rpart(Surv(pgtime, pgstat) ~ age + eet + g2 + grade + gleason +
> ploidy, data=stagec)
Result:
1) root 146 195.411600 1.0000000
2) grade< 2.5 61 4...

jail + postgresql + System V IPC
HI everyone,
I have resently installed a jail environment on my freebsd box, and had some
problems getting postgresql running under it.

set jail.sysvipc_allowed to be 1 using sysctl in order to make postgresql
run.
However man jail gives me:
jail.sysvipc_allowed
This MIB entry determines whether or not

Forced inclusion of varaibles in validate command as well as step
Dear prof. Harrell,
I'm not able to use the force option with fastbw, here an example of the error I've got (dataset stagec rpart package):

> fbwstc <- fastbw(fitstc,rule="aic",type="individual")
