| Subject | st: Cox Regression - flat region resulting in a missing likelihood |
| Date | Mon, 29 Apr 2013 20:16:47 +0200 |
Dear all, I set my data stset and then I tried to run a stcox and got the following error message " flat region resulting in a missing likelihood r(430)"; There should be reasonable variation in my depended variable, which is the time measure in months until death and my data is non- censored, meaning every observation unit experienced the "event". I would be greatful for some input.
