*"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?"*

## SPSS Python Syntax Example

***Run REGRESSION repeatedly over different dependent variables.**

begin program.

import spss,spssaux

dependent = 'v1 to v4'

**# dependent variables.**

spssSyntax = ''

**# empty Python string that we add SPSS REGRESSION commands to**

depList = spssaux.VariableDict(caseless = True).expand(dependent)

**# create Python list of variable names**

for dep in depList:

**# "+=" (below) concatenates SPSS REGRESSION commands to spssSyntax**

spssSyntax += '''

REGRESSION

/MISSING PAIRWISE

/STATISTICS COEFF OUTS R ANOVA

/CRITERIA=PIN(.05) POUT(.10)

/NOORIGIN

/DEPENDENT %s

/METHOD=STEPWISE v5 to v14.

'''%dep

**# replace "%s" in syntax by by dependent var**

print spssSyntax

**# prints REGRESSION commands to SPSS output window**

end program.

***If REGRESSION commands look good, have SPSS run them.**

begin program.

spss.Submit(spssSyntax)

end program.

## 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.

I think there is a typo in line 8 of the Regression over Many Dependent Variables python example. I think it should be depList not deplist.

You're right. I'll fix it straight away. Thanks for letting me know!

Thank you for sharing it.!! it's really helpful to run regression analysis at once.

My only concern is how to run this python syntax when we have multiple filters on it.

Can you please suggest.

Thanks in advance.

Hi Amirul!

What do you mean by "multiple filters"?

You can have only one FILTER in effect at any time.

Please clarify.

Thanks!
