Subject:      Syntax question?
Content-Type: text/plain; charset=us-ascii

I'm using spss for windows, and have a 3x2x2 (with the first two factors
within subjects, and the third between) with a covariate.  The full
factorial model results results in the covariate being significant in
only one interaction.  I want to keep that interaction in the model, but
drop all the other nonsignificant covariate interactions, and re-run the
anaysis.
 
My question: first is this possible with spss?  It sure doesn't seem
possible with just using the windows, and looks like I'll need to get
into the syntax.
 
If I am using the syntax, what command allows me to specify what
covariate interactions are allowed into the model?
 
Any help would be much appreciated,
 
Reid
