Dear Matthew,
Do you mean a variable that contains only a single valid value? Can't you try with a small test data set what happens? It seems that sum.2 applies to within-case summation, not summation within a variable over cases. See
data list free /tinkywinky.
begin data
'' '' '' '' '' '' 1
end data.
comp dum=0.
agg
/out *
/bre dum
/lala=sum.2(tinkywinky).
exe.
HTH,

SPSS IBMers!
If I use the sum function in aggregate are all values included. In other words, if there is a category that only has one value, is that included in the sum, or do I need to use sum.1 as I would in a regular compute statement to be sure that cases with only one value are included in the sum.
Thanks!
Matt
