"Partially cumulative" yields are given O053300200005 when in dependent and cumulative yields can only be O053300200006 determined with rather large uncertainties, but the O053300200007 result for a constant ratio of independent-to- O053300200008 cumulative (I.E. Parttially cumulative) yield is O053300200009 considerably more accurate. O053300200010 -By author.
