Comparing Regression Models

#1
Hi,

I wonder if anyone can help, I want to compare two linear regression models with each other but have no idea how to do it.

I have two groups (one group completed Task A than B, second group Task B than A).

I split the SPSS file to analyse by group, all the variables are the same but the correlations come out different dependent on group so now I would like to try and compare the groups to see if one model is better than the other?

Would appreciate any help!

Thanks

I'm not an spss guy, so can't give advice on that software, but if you have two fitted models then you have the info required to conduct a likelihood ratio test
