Subject:      Re: Fit 2 Models with 1 PROC REG, possible ?
Content-Type: text/plain; charset=us-ascii

You can have multiple MODEL statements in the same call to REG.  So...
 
PROC REG DATA=ANTONIO OUTSET=OUT1 NOPRINT ;
         MODEL Y= X1 X2 X3 ;
         MODEL Y= X2 X4 ;
         BY ID ;
 
Note though, that observations with missing values on ANY of the
variables will be excluded from all analyses (that is, an observation
with a missing value for X4 will not be included in the first model,
even though X4 isn't part of that first model).
 
Gratuitous comment: check out the _Enhancements_ book for extra model
statistics to output that you might be interested in (like adjusted R^2s
and SEBs for instance).
