Unleash the power: Global 25 test drive thread

Ancestry modeling enthusiasts, feel free to do your best (or worst) with these datasheets and share the output, whatever it might be, in the comments below:

The Global 25 is a more powerful version of the Global 10 ancestry analysis (see here). If all goes well in the comments, it’ll soon be offered for free to those who already have Global 10 coordinates. After that, we’ll see what happens.

Below is a quick attempt to model Samara Yamnaya with its Global 25 coordinates using nMonte2. Hmmm…interesting stuff.

Obviously, this makes a lot of sense, but it’s somewhat different from my recent models of Samara Yamnaya using methods based on formal stats (see here and here). In the end, only ancient DNA from the steppes and Caucasian-Caspian region will settle this issue when enough of it is sampled.
Update 10/02/201: As per our discussion in the comments, in most cases it might be useful to restore the variance of the raw data (like in the datasheets here and here). This can be done with the EigenScale.R script available here. You’ll also need a text file of the relevant eigenvalues, available here. Instructions on how to call the R script are here. Below is the same model of Samara Yamnaya as above, except using the “restored” data. The result is very similar, albeit a little cleaner.
