Stset with durations.
hello i have wide format data with different dates which i used to create different DURATIONS since the begining of observations.
i am hesitating between 2 setup methods.
To set up stata, i use the time duration until last news DURATION1 and as failure i use the duration until death for those who died DURATION2.
So i do:
stset DURATION1, fail(DURATION2)
I had doubts so i tried another way.
I use DURATION2 but i replace missing values for those who don't die by the value of DURATION1 and i create a dichotomous failure variable
This leads to:
stset DURATION2modified, fail(dead)


The results are different and i am enclined to use the second method. Could anyone give me a feedback?
thank you
Mathieu
