Hi all,

Apologies if this is very simple.

I'm trying to run a recurring-event survival analysis using panel data. I used to following code for my stset:

stset time, id(participantid) failure(event=1)

time = the number of days of follow-up (between 1-3000)
event = an indicator of whether or not the observation was an event of interest

Once I do this, Stata informs me of the number of subjects and the number of failures in single-failure-per-subject data, and adds _st _d _t & _t0 to my variable list.

My issue (at least, I think it's an issue), is for every observation is the second or upward event for any given participant has an _st value of 0, and a missing value for each of _d _t & _t0. Does this mean these observations are not included in my analyses? How do I set up my stset correctly to ensure I'm capturing these observations?

Thanks in advance,

Alexander
