st: Survival Analysis: stset-command

[Philipp <philipp_124@gmx.de>]

Hi there,

I want to do a Survival Analysis but I have a problem using the stset-command. (Using Stata13.0/SE)
I want to look when households purchase real estate (ho=Home Ownership).
My panel data looks as follows:

id	age 	year ho	cens	age_enter	age_exit ...
1	32	2001	0	0	32	33
1	33	2002	0	1	32	33
2	27	2004	0	0	27	28
2	28	2005	1	0	27	28
3	45	2003	1	.	45	47
3	47	2005	1	.	45	47
...

I'm using:
drop if cens==.
stset age, failure(cens==1) id(id) enter(age_enter) exit(age_exit)

The Kaplan-Meier-Function goes from 1.00 to 0.00 for the full data set. But I want it to go to the probability of IDs without home (in the example .5). So there must be a (huge) mistake :/

Can someone help me please? 

I'm not sure if my command is specific enough for Stata that it gets that I want only the age 28 of id 2 as "event".

Thanks for your help!
