You could tell us more about your data, but it sounds like you should use one of the estimators for panel data, including xtlogit, xtprobit, or xtcloglog if the dependent variable is highly skewed. Check out the xt set up and the various estimators in the Stata manual.

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.
