Comparison of Parameterizations
General comments (cont.)
My view:
·Sample mean scale (unified family) has easier scientific interpretation than the error spending scale which has a purely statistical interpretation that, in my experience, is poorly understood by both users and researchers
·The parameterization of the unified family produces a more useful grouping of designs on some level than does the parameterization of the error spending family
