GENERAL NOTE: * 05/28/2014: We decided to do handle weights consistently to SPSS in an operation-specific manner, i.e., we (1) round instead of casting where required (e.g. count), and (2) consistently use fractional weight values elsewhere. In case a count-base interpretation of weights is needed, just ensure rounding before calling CM/COV/KahanPlus.- See Also:
