Re: [R] Difference in coefficients in Cox proportional hazard estimates between R and Stata, why?

In the Cox regression case, the probable explanation is that you have ties in your data; Stata and coxph may have different defaults for handling ties. Read the manuals! The difference in sign in the other cases is simply due to different definitions of the models. I am sure it is well documen

[R] Difference in coefficients in Cox proportional hazard estimates between R and Stata, why?

Dear R users, Hi, thank you so much for your help in advance. I have been using Stata but new to R. For my paper revision using Aalen's survival analysis, I need to use R, as the command including Aalen's survival seems to be available in R (32-bit, version 3.1.0 (2014-04-10)) but less ready
