fitting problems in coxph.fit
Dear Thomas & Dear List,
the fitting function `coxph.fit' called by `coxph' may fail to estimate
the regression coefficients when some values of the design matrix are very
large. For example
library(survival)
### load example data
load(url("http://www.imbe.med.uni-erlangen.de/~hothorn/coxph_fit.Rda"))
method <- "efron"

number of copies
I'm looking at memory efficiency for some of the survival code. The
following fragment appears in coxph.fit
coxfit <- .C("coxfit2", iter=as.integer(maxiter),
as.integer(n),
as.integer(nvar), stime,
sstat,
x= x[sorted,] ,
...
Does this make a second copy of x to pass to the routine (my

[patch/unstable] page table cleanups
Hi,
In many places xen uses "unsigned long" instead of the l*_pgentry_t
types to pass around page table entries. Here is a patch which fixes
this in a number of places (mostly in shadow mode code). Thats what
I''ve trapped in so far, maybe more of these patches follow.
Fixing this is needed for adding PAE support to xen. In PAE paging mode
the page table entries are 64 bit

chroot sftp-server [PATCH]
I'm working on setting up a semi-trusted sftp service, and to get it
working, I need chroot capability.
I've taken the /./ wuftpd magic token code from contrib/chroot.diff and
put it into the sftp server. The main problem is that privileges have
been dropped by the time the subsystem is exec'ed, so my patch requires
that sftp-server be setuid root. Not ideal, I know, but I drop all

Capture warning messages from coxph()
Hi,
I want to fit multiple cox models using the coxph() function. To do
this, I use a for-loop and save the relevant results in a separate
matrix. In the example below, only two models are fitted (my actual
matrix has many more columns), one gives a warning message, while the
other does not. Right now, I see all the warning message(s) after the
for-loop is completed but have no idea which model
