Default determining median survival time using Stata exponential distro



First, let me say I am a complete noob to biostatistics and this forum, but am now trying to jump into studying biostats using Stata.

I need to determine a median survival time and other percentile info using an exponential model in Stata. I either cannot get this to work, and/or simply don't understand how to interpret the output.

I currently get just a hazard ratio or coefficient, SE and CI if I use the streg command. This command only appears to work after using stset to get Kaplan-Meier output. stsum gives me the identical output as it does after the stset command, so I am not sure I am getting a new median reported based on an exponential model; I don't think I am.

Any thoughts?
