Elimination of outliers when calculating population averages on GEDmatch

[reboun]

How accurate is to eliminate the outliers when calculating a population’s autosomal structure? Think of a population which is really diverse and 40% of the population is in the outlier range. Isn’t 40% is a huge percentage to neglect?

It depends on the sampling. The sampling can be biased, so you don't know the reality. If you see extreme diversity you can assume that the problem exists, but not the size.

Yes, but elimination of outliers make a diverse population seems less diverse than it is. I guess it is inaccurate. Some populations are very diverse thanks to the fact that they have always been on immigration roots of tribes.

Which population consists of 40% of outliers? Suburbs or Paris and Brussels, you mean?

I know what you are aiming for though and it's simply innacurate. 40% of ethnic Turks certainly aren't genetic outliers. Balkan Turks aren't outliers and have typical for them genetic structure.
You are zero ethnic Turk and thus suffer from identity crisis.

Makes no sense to include people like you in autosomal study of Turkish population. And if you are implying 40% of Turks in total are consisted of foreigners like Bosniaks, that is obviously nonsense.

Okay, this is your opinion, which I respect. By the way, it might sound ignorant but what about suburbs of Paris and Brussels?

Can you please finally stop with this bullshit? You don't have to open a thread for every nonsensical question that comes to your mind.

Contrarily, elimination of outliers increases the accuracy. If a population has 40% of outliers then that 40% is the percentage of ethnic minorities in the population for sure.

Stearsolina, I don’t think it is nonsense. About 40% of Turkish population might consist of people with non-Turkic and non-native Anatolian background.

Anatolian Turks, Balkan Turks and other Turkic minorities in Turkey are ethnic Turks. Non-Turkic minorities are not outliers because they are not part of the ethnic Turkish population. They are Turkish citizens not ethnic Turks. That 40% seems inflated. Do you include all Balkan Turks in that number. Also you can identify as a Turk and nobody would reject you as a Turk but you shouldn't overdo the diversity part by including different ethnicities as Turks. They have their own different identities but the only identity for the Anatolian Turks is Turkish.

I thought of people who have non-Turkic ancestors in last 2-3 generations. I guess they make 40% of Turkish population or no?
