Identifying relationships between independent variables

Postby jasonharris1 » Wed Jul 22, 2015 2:28 am

Hi-- Is there a way a have SPSS automatically evaluate potential relationships within independent variables? For example-- if I have January Sales and February Sales and I'm trying to predict monthly profit growth, neither January or February sales on their own will be predictive, but February Sales/January Sales may be highly predictive. Right now, I am calculating these by hand as additional data columns but is there a better way where SPSS will automatically test for inter-relationships and select those that are predictive?

Thank you,
Jason
