I'm looking for a way to show how two continuous signals are correlated
over time. In other words, if x(t) and y(t) are correlated signals (with
some phase lag between them), does that correlation change over time?
(and if so, then how does it vary)
What I'd ideally like to get is something like

Ralph Johnson and J. anthony Blair are the authors of _Logical
Self-Defense_. (I know, I did a year of grad study in Informal Logic with
them.)

I guess I have to accept there is no way to customize within * between
interactions in GLM. Thanks for the tip using regression, but I think in
future I'd rather try to give a meaning to the default interactions ;-)
This leads me back to the second part of my original question: Is there
some good
What interpretations can be made from bipolar factors (factors consisting of
negative as well as positive loadings on items)? When calculating the factor
score for bipolar factors, should the negative sign be ignored?
