This is not a SPSS-question, but ...

I think that there are special problems if sample selection and matching
of a "control" group are done on the dependent variable instead on the
independent variable. Can someone point me to "authoritative" references
_discussing_ the respective problems (or even merits) of such a sampling
approach in some detail?
