Dear all,
I'm a relatively new Stata user doing discrete event history models with two questions regarding data handling. I have browsed manuals and the list archive but cannot seem to find an answer to my questions that works.
My data looks like this.

id  time  event  indep1 .....
1    1       0        1
1    2       0        0
1    3       1        0
1 4 0 0 etc.....

1) How do I drop the observation for time 4 (after org1 has 'failed') and it should no longer be part of my cloglog or logit models? 2) I want my indep var to work for two periods. How do I do that without making it work for period 3?

Best regards,

Anders
