I am using SPSS and have about 300 variables (categorical, scalar and ordinal) to model. I want to an Easy / Quick way to create interaction variable composites for Logistic Regression where interactions exist. R does this automatically and creates about 158 composites (variables that have interactions) - there does not appear to be any automated way to create and input interaction variables in SPSS; having to manually input and or test these 158 composites every time I run a new model is going to be A LOT OF WORK!! Any suggestions on a quick way to do this?
