Here is a very preliminary PCA using HarappaWorld calculator's spreadsheet. I have also added a couple of forum members(based on their scores posted on this really old thread from 2015) just to see where some people fit in. Note this does not use the mother-of-all data Khana has put together. This is just a baby first step. If it is useful, I might create a 3D version for it, but it already does account for 93% of the variance.

Purple=IA/IE speakers

Green=Dravidian speakers

Orange=AA speakers

Forum members are Red pluses.

Revision 3: added Kush, Xehanort, Gyanwali, and Mingle. Also, fixed color coding issue where Srilankan and Goan were darkgreen instead of purple.

Biplot (no changes)

Version 2

Revision Version 2 - added Reza family and Jortita, also added 95% ellipse

Note that the graph has flipped... it sort of looks like a scorpio!

Biplot - same as before

Version 1:

Using the biplot, we can see that the 1st quadrant has SouthIndian component, 2nd quadrant has Baloch component, 3rd quadrant has Caucasian+NE-European+NE-Asian+SW-Asian, while the 4th quadrant has Papuan+SE-Asian pull.
