Survival tree analysis

I need to perform a survival tree analysis. I have :
- 1 independant variable X (numberic variable)
- 1 dependant variable Y (overall survival time (censored data))

How do you do to perform it? Is SAS software can do it?
Can we split only in 2 nodes or more nodes for the same variable is possible?

Thanks in advance for your help.


Ninja say what!?!
To show you exactly how to do it will take too much time and space here. I would suggest looking up kaplan-meyer curves. You could also try Cox-proportional models, but I wouldn't recommend it for someone starting out.
