st: Kaplan Meier graph in longitudinal data

[Deepa Aggarwal <da.aggarwal@gmail.com>]

 Hi All,

I have the following longitudinal data :

 id     d_entry           d_censor         status          age       x2
 1      20jan2008     22jan 2008        0               62          0
 1      22jan 2008    24jan 2008        0               62          0
 1      24jan 2008    26jan 2008        0               62          1
 1      26jan 2008    28jan 2008        1                62          0
 2      13jan 2008    18jan 2008        0               70           0
 2     18jan 2008    20jan 2008        0               70           1
 2      20jan 2008    24jan 2008        0               70           0
 2     24jan 2008    26jan 2008        1                70          1

 Here id is patient id number, d_entry is the date of entry,  d_censor
 is the date of censoring, status is the censoring variable, age is
 fixed for each id, x2 changes with time for each id.

First I stset the above mentioned data by using the following command:
stset d_censor, id(id) failure (status==1) origin (time d_entry)

Now I want to get a Kaplan meier graph . I know if there is one event per
id, then sts graph can be used.
But in recurrent event models, what command should be used?


 Thanks for your consideration.
