Hi Kim

provided that the 'measure-moments' are ordered the following syntax should work:

DATA LIST LIST /id flu stress stresswk fluwk. BEGIN DATA 1 1 0 1 1 2 1 1 2 2 3 1 0 3 3 4 0 1 4 4 END DATA.

If LAG(Stress) = 1 flag = 1. exec. Select if flu = 1 AND flag = 1 . exec.

Hope this helps, Christian

Hi,

This is the data-format:

id flu stress stresswk fluwk 1 1 0 1 1 2 1 1 2 2 3 1 0 3 3 4 0 1 4 4

I want to select cases if: flu=1 AND stress=1, but stress=1 has to be one measure-moment before flu=1. So in the example above, only casenumber 3 has to be selected, because 'stress' was present one measure-moment before the occurence of 'flu'.

I would appreciate your help.

Kind Regards, Kim Smolderen Tilburg University
