Various methods were proposed to understand the linkages in an input-output system; however, many have focused only on the identification of key sectors in the economy. An alternative approach, identifying analytically the importance of elements and combinations of elements was proposed as a...

Dual scaling of a subjects-by-objects table of dominance data (preferences, paired comparisons and successive categories data) has been contrasted with correspondence analysis, as if the two techniques were somehow different. In this note we show that dual scaling of dominance data is equivalent...
