Investigating 'data error' after stset

[jim templeton]

Hi everyone,

I managed to st set my data to perform survival analysis. However, after performing the 'stset', there are observations which end on or before (enter):

Survival-time data settings

         Failure event: validinf==1
Observed time interval: (0, person_time]
     Exit on or before: failure

--------------------------------------------------------------------------
    165023  total observations
      2,462  observations end on or before enter()
--------------------------------------------------------------------------
    175,544  observations remaining, representing
      3,569  failures in single-record/single-failure data
  1,051,172  total analysis time at risk and under observation
                                                At risk from t =         0
                                     Earliest observed entry t =         0
                                          Last observed exit t =     24.00

Could anyone help with the command which will allow me to investigate these observations?
