changes in coxph in "survival" from older version?
Hi all,
I found that the two different versions of "survival" packages, namely 2.36-5
vs. 2.36-8 or later, give different results for coxph function. Please see
below and the data is attached. The second one was done on Linux, but Windows
gave the same results. Could you please let me know which one I should trust?
Thanks,
...Tao
