STATA allows an analysis using data in the counting process notation:
stset stop,failure(dead=1) entry(start) id(id)
where start and stop are the start and end of each time interval, and where there can be many (non-overlapping) intervals for a subject.
Is it valid to use streg with data in this form, or should it only be used with stcox? I.e. is the likelihood calculated in the correct way when streg is used?
