Notes on Weighting
EWEIGHT and EWEIGHT2 - These two equilibrated weights are simply equal. There is no difference, except for the absolute values obtained, which are scaled by 1.5 ratio (percentages should not change). The reason to include both is that some researchers like an equal N of 1000 and others prefer 1500.
