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
