In the spreadsheet you can see the optimal solution if one retains only 10 dimensions in which case 45 clusters are inferred. Previously, I retained 47 dimensions, and got only 35 clusters in the optimal solution: less is more.
In comparison to the previous analysis, I can detect some interesting changes:
I am now studying how to choose the optimal number of MDS dimensions to retain, so I will not report any individual data about this to project participants. I just wanted to let everyone share in the excitement.
- Spaniards and Portuguse are split from Tuscans and are joined by some French and North Italians; the rest of the French stay with White Utahns, and the rest of the North Italians stay with Tuscans.
- Romanians too get their own cluster
- Turks are split from Assyrians/Armenians.
- Germans are split from Scandinavians, with 1 sample from either population going to the other population.
- The relationship between Cypriots and South Italians is retained, but most of the Greeks (many of whom were borderline between the Tuscan and South Italian cluster) go the Tuscan way.
