I have created a fairly comprehensive macro that undertakes model comparison, analysis and graphing of difference score regression (situations where there are two related predictors of a dependent variable, say expected versus actual levels of something). The outputs are based on Jeffrey Edward's work in the management field. Outputs compare algebraic, absolute and squared comparisons up to third order models, and graphs response surfaces and the like. I attach scoping document. Interested users are welcome to the macro, just contact me.
