“I have a data file on which I’d like to carry out several regression analyses. I have four dependent variables, v1 through v4. The independent variables (v5 through v14) are the same for all analyses. How can I carry out these four analyses in an efficient way that would also work for 100 dependent variables?”

Description
- That this syntax uses Python so you need to have the SPSS Python Essentials installed in order to run it;
- The syntax will simply run a standard SPSS regression analysis analysis over different dependent variables one-by-one;
- Except for the occurrence of
%s, Python will submit to SPSS a textbook example of regression syntax generated by the GUI. It can be modified as desired. - The TO and ALL keywords may be used for specifying the dependent and independent variables. The entire specification is enclosed in quotes.
- As a test file for this solution, you could use supermarket.sav.
