Log regression forward stepwise processes

Postby Jasmine » Wed Oct 01, 2008 8:43 am

Hi everyone,

I was wondering whether it is possible in spss 16 to execute forward stepwise model when doing a logistic regression. How do I do that?

Under the method dialogue choose forward. Or if you are using syntax, use /method = fstep var 1 var 2 etc.

If you are using syntax, you will also have to specify your cut point - usually .5 and your p value for entry PIN and exit POUT.

Please note that stepwise procedures are sometimes frowned upon.
