Sorry to jump into this but I dont see whay Dan cannot
use z-scores as a dependent variable, even if z-scores
are standarized. Wouldnt it depend on which are the
independent variables used?


No, no reason why not, and it actually doesn't depend on the  
regressors. If you run

z(y) = a + b X + u

b is the number of standard deviations of y in response to a one unit  
change in X. If that makes sense as a way to express dY/dX, fine. If  
you run

z(y) = b z(X) + u

you are calculating the 'beta coefficient', i.e.   regress y X, beta.
