Tony,
Y=XB+U
Where each of these are matrices:
Y (n x p)
B (p x k)
U (n x p)
n= number of respondents
p= number of dependent variables
k= the number of columns in the design matrix (including constant vector).
For additional info I refer you/him to the algorithms:

All,

A colleague asked me what should be a simple question and I have no answer for him.  He has some basic manova syntax (below) and he would like to know what the equation from such a model would look like.  Excluding all of the marginal means, etc., can anyone answer that question for him?  Thanks very much.
