I have a censored interval that i am analysing with Proc PHREG. I have chosen this over Proc Lifetest as i have recurrent events and clustered events that i need to account for. However, Proc Lifetest will give Mean and Median and quartile outputs, but how would i get this using Proc PHREG?
Not sure if this is the right way, but i got the survival outputs of the analysis to be entered into a data table and could read off the 75%, 50% and 25% figures for each factor there.
