Hi to all.
 
I would like to ask the following:
 
For survival data (before stset) how would I indicate censored observations?
For the observations with complete information (entry/exit dates and outcome) I have coded the outcome as 0 or 1 but I am not sure how to code patients lost before the end of the study. 
Censored observations also have just entry dates. Would exit date (for censored observatiosn) be the end of study date or date of last assessment in which patient(s) went missing? 
 
Any comments would be appreciated.
 
Thank you,
 
Nick
