Competing risk model error message

[Buyadaa Oyunchimeg]

Dear all,

I am trying to run a competing model with STATA and having the following error. I would really appreciate if anyone may help me.

Thank you
Sincerely,
Oyun

error message:

-stcrreg- does not allow you to have different variables to designate the primary failure event and the competing events. What you need is a single variable that takes on different values for the primary failure event, each competing event, and each censoring event. So you would need to do something like this (not tested):

gen failure_var = 0
replace failiure_var = 1 if chf == 1
replace failure_var = 2 if death == 1 & time_death < time_chf

stset time_chf, failure(failure_var = 1)  id(id)
stcrreg i.age i.gender, compete(failure_var = 2)

Note: I don't know how you have defined the time_chf variable, but based just on its name I fear it is wrong. The variable you need in that part of the -stset- command must contain the time of occurence of whichever event occurs, whether it is chf, death from other causes, or end of observation due to withdrawal/end of study, etc. If you don't have a variable like that, you need to create one. If time_chf is in fact such a variable, then you are OK using it in this way (though if it were my project, I would give it a name that suggests its generality.)

Thank you so much prof.Schechter for valuable guidance.
It seems I have to create time variable which contains the time of occurence of whichever event occurs first as you suggested.
