From Biplot Tools, click Which Won Where/What. The following will appear on the biplot:
- a polygon that is drawn on entries (entries 5, 7, 4, 3, and 2) located away from the biplot origin such that all other entries are contained within the polygon, and
- a set of lines that are perpendicular to the sides of the polygon.
- each perpendicular line is actually the equality line between two testers the polygon side connects (see compare two entries).
- In this example, the perpendicular lines divide the biplot into 5 sectors
- A tester falls inevitably into one of the sectors
- The vertex entry for (not necessarily in) each sector had the greatest values for all testers falling within that sector. In this example, Entry5 wins for Testers 5 and 7, and Entry7 wins for Testers 1, 3, 4, 6, 8, and 9. Thereby the testers are divided into two groups based on the winners.
- Entry5 and Entry7 performed similarly with regard to Tester2.
- The choice of a SVP method does not affect the which-won-where pattern.
