(((Davidski)))

[Leto]

i think he's an Eastern Euro wishing to be a Western one, and sucking up to them.

the only proper averages he made in G25 are for NW Euros. also, his Yamnaya/WHG/EEF model is NW-Euro centric, and doesn't even work well for his own people, the Poles.

He is Polish living in Australia. Don't know if he's a first gen immigrant or was born in the country. His English is correct.

if you are interested in the genetics of Central and East Europe and the Balkans, G25 is useless for you.
Davidski is biased against this part of the world, and his tool will be uninformative and in some cases even misleading and wrong for you.
yet he has no problem taking money from East Europeans and Balkanians.

see how for example, he didn't include a single Central Greek in his tool, although a dozen are available.

if i'm interested in Central Greeks, on gedmatch i can check the results of all the academic Central Greeks, plus i can dig through the database and find even more real life central Greeks.



you can try to ask him on his blog. i wonder how he'll react.

I don´t think is useless. Did you already try it?

Davidski's Russian, East Slavic averages from G25 are okay. I think they are academic.

Most are HGDP.

I have noticed a lot of these Polish guys like the Germans. Peterski included.

trying it would require giving money to Davidski.
when he fixes his averages for my part of the world, and explains what the hell he was thinking while making the old averages, i might consider it.

some Balkan members already bought it, just to get that Yamnaya model which doesn't even work properly for East Europeans, and just to realize the majority of Balkan samples are missing from his tool.
Aspar asked him to fix his Macedonian average, he ignored him. Decius asked him about the Serbian samples, Davidski lied to his face about some "technical issues". I can learn from their mistakes.

I'm not a fan of G 25. I told him that. I do like his IBD Analysis but he hates to run those.

I'd heard that he's in Australia but never seen confirmation. It wouldn't surprise me though as his language/humour/wit is that of someone from these parts, not Eastern Europe.

But this is a problem with Davidsky election of some references, not a problem with G25 itself. I think the tool itself is good, even the maths behind it and the statistical package must make this tool and those coordinates much more accurates.

He admitted to me it is not good for someone with mixed ancestry like myself especially a 4 ethnicity model. Then he told me when you go beyond six ethnicities you overload the algorithm.

[Ion Basescul]

he definitely did that.

these are the official labels of Montenegrin samples from the study. Yes, they are labeled a bit randomly, there is no Montenegrin2 or 3.
1,4,5,6,7 are in g25.

Montenegro1 Montenegro1 0 0 2 -9
Montenegro4 Montenegro4 0 0 2 -9
Montenegro5 Montenegro5 0 0 2 -9
Montenegro6 Montenegro6 0 0 1 -9
Montenegro7 Montenegro7 0 0 2 -9
Montenegro9 Montenegro9 0 0 1 -9
Montenegro10 Montenegro10 0 0 1 -9
Montenegro11 Montenegro11 0 0 1 -9
Montenegro14 Montenegro14 0 0 2 -9
Montenegro15 Montenegro15 0 0 1 -9
Montenegro17 Montenegro17 0 0 1 -9
Montenegro19 Montenegro19 0 0 1 -9
Montenegro20 Montenegro20 0 0 1 -9
Montenegro21 Montenegro21 0 0 2 -9

Did you guys try converting the files to 23andme raw data and sending them to him?
I've done that for all the samples that I've sent from Moldova and Romania, and he's never ignored any. He also responds to all my emails when I ask for help and even created the imputed coordinates for my family free of charge.
