This thread is for posting the qpAdm results for our Iranian members, and subsequent discussion. As previously mentioned, fits with chisq values over 2 and tail probabilities less than 80% should not be taken too seriously.

I have purposely kept the left pops and right pops the same for all members, so that the fixed path values (100% modeling) between the various members can be kept comparable. Although some members may not have gotten good fits, their fixed path values are nonetheless informative, and I may attempt a qpAdm based PCA and dendogram, as I believed I have figured out a way to do that. This would be a first as far as I am aware, and it would be interesting to compare the clustering based on it, to the usual ADMIXTURE based PCAs out there (recent ancestry). We may be able to get clustering on a more ancestral level doing so.

A general comment on results obtained using formal methods. I have noticed that some members get uptight (directed at non-Iranian members) when analysis based on formal methods reveals results/ancestry that does not conform to their preconceived ideas/beliefs, or ADMIXTURE, which is based on recent drift. Those members should remember that their written records only go back a few hundred years at best, and that the further back we go in time, the higher the probability that some of your ancestry will deviate from the average ancestry of your ethnic group. This happens for reasons such as voluntary integration of individuals from one ethnic group into another, or forced integration.

I will circle around and re-run the Pashtun members using the same exact base pops used for Kurds and Iranian members under this thread. I will then move on to the other project members. Once I have done almost everyone, I will work on the PCA and dendogram. It will take me a little while to get to everyone, as I do this on a time-permitting, non paid voluntary basis.

Down the road, I hope to start modeling members using some of the newly sequenced genomes, which I incorporated into my dataset when they first came out, but have not had the time to analyze.

From our Iranian members, Jesus was the only one who obtained excellent fits using my base populations. Thus his results are the most realistic.
