I am trying to analyze a continious data set with ridge regression. Is there any way of doing this from the menus in SPSS without using any syntax. Or could you please explain me how to use a syntax for ridge regression. I have a very limited time to complete my project. I am using SPSS v20 Portable and tried to do ridge regresiion from CATREG menu but it doesn't work well because of continiuity. Please help..
