ZC Diffs or raw data from HB if I want to do a regression?

If I want to do a regression with my HB values from a ACBC, what value do I have to take? ZC Diffs or can I also use the raw data?

Assuming your regression is across people (rather than within people), zero-centered diffs would be better, since they do a better job of placing them on approximately the same scale.
