Dear All,
My question to you is why does stcox sometimes reports “Cox regression -- no ties”? I think in theory there should be no ties, but in reality there always are, right? Is this is a result of colinearity? If it is, why stcox still produce standard errors, hazard ratio, etc.
Thanks a lot,
Piotr Paradowski
