If you have single record data, run -summary- on your failure time variable. If you have multiple record data, keep only one record for each person first and then run -summary-.

Hello Statalisters,

I was wondering if you have used the stdes command and were able to get a standard deviation for time at risk in addition to mean, median and range. I am not sure if that is at all possible. Is there another command one can use to get the SD? Thanks a lot!
