I want to use Cox proportional hazard model with time varying covariates to estimate mortality hazards. In the program, I need to specify a variable, t0 indicating the time of the beginning of the interval. The data I have is a longitudinal data with 5 panels. Each respondent should have 5 lines of data. What should the value of t0 in the first line of the data for respondent i be given? There is no clear explanation in the manual. My hunch is that t0 should be the first year that we observed the respondent in the survey. For example, Respondent i was first observed in 1989 and his age was 60 at that time. Then t0 in the first line of data for respondent i should be 60. Am I right?
