coxph failure
...31.05389866 900.67627778
Unfortunately exp(900) = Inf, and that pretty much does in my C routine
right there; within another iteration there are NA values littered about
and the return value for the coefficients is all NA.
If instead you fit a smoothing spline to the data
coxph(Surv(TTFAIL, FFAIL) ~ pspline(CREAT6MO, df=4), data=anomaly1)
the fitted response is essentially linear from 0 to 5 before turning
upward, but it never gets outrageous due to the shrinkage towards
linearity.
Catching this type of issue with an extremely skewed variable
(creatinine^4) would be very hard to do reliabl...

help isolinux with multiple iso-images on disk?
...I want to build a cd with isolinux and its boot-menu, but
on the cd I have various (small) iso-images as files
and I want isolinux to provide me the menu-switching facility between them.
Can this be done and if so, how?
I managed to have isolinux working with various floppy-images on the cd but
ffailed completely with cd-images on the cd.
Thanks, Juergen
