Cross-correlation is defined for a single series -- the second series for ordinary correlation purposes being the first series dispaced by a phase and tending to have meaning when the first series repeats cyclically -- is this what you really mean? The fact that you talk of two series makes me think you want ordinary correlation as per Statistics::Basic::Correlation
