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).

HTH,
