Dear all, 
I use -stci- to calculate median survival time but no results are generated:
. stci, rmean
        failure _d:  Outcome == 0 1 2 3 4
   analysis time _t:  (End-origin)
             origin:  time Start
  exit on or before:  Outcome==5
                 id:  pid

             |    no. of  restricted
             |  subjects        mean      Std. Err.    [95% Conf. Interval]
-------------+-------------------------------------------------------------
       total |      9966           .(*)          .            .          .
(*) largest observed analysis time is censored, mean is underestimated

Is that a bug in my software or I stset my data wrongly? Thank you very much in advance.

Best regards, 
Kai Huang
