discrepancies between stata and r for a cox regression
Hello
I would like to develop the use of R.
Trying R and more particulary the cox model, I am surprised by discrepancies between results with stata and R for a cox model
With the same data base, I get a hazard ratio (4.82) that is not the same obtained with stata (4.52)
You will find attached the file leukemia.dta I used (Stata)
Here are the codes for R
