As far as I know, the best method would be to use an SEM program, for example, Amos, which you may have installed with spss, because you can constrain coefficients to be equal and test the change in fit. I don't think that can be done in any GLM structured program. If you use an SEM program, the data should be in wide (multivariate) format rather than long format. Equality requires both slope and intercept equality and, ideally, equal residual variances.

Subject: Multivariate regression
Hello,
I am using SPSS 20.0 and am running a multivariate regression using the GLM procedure. I would like to know how to test whether the relationship between one independent variable (X1) and one dependent variable (Y1) is equivalent to the relationship between another independent variable (X2) and another dependent variable (Y2). In other words, if (X1 Y1) = (X2 Y2).
Does anyone know how to write this using syntax? Thank you for any help.
