SPSS is not very good about including built-in procedures for anything beyond very standard social science statistics. However, what you want to do (or something like it, I m not familiar with the method) is apparently feasible if you transform your variables and then run a linear regression, as documented here (a powerpoint file).

If it isn t strictly necessary to use SPSS, you re probably better off using something like R where what you want is more likely to be formally implemented. Check out the season package.
