|Subject: ||Help with Survival Analysis Censoring|
|Content-Type: ||text/plain; charset=ascii|
May be one of the statisticians can help me understand this.
I am trying to perform a survival analysis.I am totally new to this so forgive me if I say sthng wrong here.
I have a set of data with subjects having a time for when the event occured.Since the event should occur all of them are censored as 0.
When I run lifetest ,I still get 3 subjects which are censored in censored summary.This is where I am confused because all the subjects had a time to event value and they were not censored as "0".
proc lifetest data=pp ;
strata trtgrp ;
Can someone provide some insight on why the censored summary is showing ppl who are censored when actually there is noone censored.
