EvilDave, here is the output with p-values for the mage commander equation. 
As I have alluded to before, I am using a stepwise procedure. I first include all 
the predictors I have available at the moment. Then I remove one predictor at 
a time, starting from the highest p-values, until all remaining predictors have 
p-values less than .10.
