Hi list,
I work with longitudinal data. Due to the structure of the data (the time 
covariate is not continuous as I have monthly data only), I cannot use Cox 
regression.  There is up to 24 records for each respondent.  Each record 
represent the status of a respondent for each month of a two-year period.  

My questions are: Do I have the correct datafile structure to perform logistic 
regression in this context?  If so, do I need to enter a command line grouping 
observations by respondent, as in Cox regression?

Thank you for any help you can provide.
