Greetings fellow SPSS users,

 

I checked the archives but couldn’t find anything that fitted this case, as
I could tell. I also searched the web but could not find anything – at
least, that I could understand.

 

I am trying to find out if there is a test to compare two (ols) regression
coefficients. Here’s the setup. Individuals have been randomized to group A
and B. They have been measured on Y (the DV) and group A have been measure
on xA and group B measured on xB. To be clear xA and xB are two different
(independent) variables. I want to compare in a simple regression (Y=c + xA
and Y=c + xB) the regression coefficient for xA and xB (bxA – bxB). Thus, I
am dealing with two different models (the same DV but different IVs) AND two
independent groups.

 

So my questions are: Is there a test for such a situation? If so, (2) can it
be implemented in SPSS?

 

Thanks in advance for time and help – Dominic
