OK.. that was helpful. Didnt know the matrix automatically found its
way into simulate.

However, my objective here is to use stepwise,pr (0.1): regress x y z
d f and to return the matrix for each run so that I in the end can see
how often the variable was selected in the model and also see whether
it had a pos or neg beta (Similar to Sauerbreis selection and
stability procedure). So preferably I'd like -simulate- to return the
final matrix for each run with its associated betas for each model.
