Craig:
Here is SPSS syntax for creating a mean-centered transformation of a variable:
COMPUTE DUMMY=1.
AGGREGATE OUTFILE='mean.tmp'
/BREAK=DUMMY
/MEANVAR=MEAN(ORIGVAR).
MATCH FILES FILE=*
/TABLE='mean.tmp'
/BY DUMMY.
COMPUTE CENTVAR=ORIGVAR-MEANVAR.
DUMMY is a variable that will the same value (1) for all cases, MEANVAR is a
variable that has the mean of the ORIGVAR variable for all cases, and
CENTVAR is the mean-centered transformation.
