Sorry, this is not a html email. And I hope you could read my table. There are 7 years and 3 subjects.
Thanks!

>You see for each patient there are multiple observations, and also there may be multiple failures(in this case - getting fine). And also some subject has gap in the data, for example patient 3 has gap in year 3 and year 4. I wonder whether I can still use streg or stcox for this setting and use ALL the observations. For example,
>
>*****************************************************
>stset t, id(patient) failure(fine) exit(time .) noshow
>stcox weight female, r
>or streg weight female, r
>*****************************************************
