Logistic regression would appear to be the logical choice--assuming that
you are trying to determine the probability of someone being in the No
(or Yes) category given particular values on a set of predictors. There
is no reason why you can't use multiple predictors.
Go to Analyze--Regresion--Binary Logistic
Enter your IVs as covariates. My understanding is that Base SPSS has
the Logisitc procedure so you should not have any problems. I would
strongly suggest you look at a good book on logistic regression before
you start. Interpreting logistic regression results can be tricky. Try
Hosmer and Lemeshow's Applied Logistic Regression.

I've installed the base system. Here's the question I'm trying to
