See http://www.anthrogenica.com/showthread.php?12782-Online-Pigmentation-Predictor . I am surprised an ethnic Turk got 13% more white admixture than me.

Wait can u explain how I do this?

:laugh:

It's different every version:

1) 99.68 % for White; 0.32 % for Intermediate; 0.00 % for Black

2) 98.25% White; 1.75% Intermediate; 0.00% Black

3) 91.85% White; 8.15 % Intermediate; 0.00% Black

Naive Bayes (Hardy-Weinberg principle applies)
This profile is 235 times more likely White than Intermediate, and 84,557 times more likely White than Black.

Predicted admixture: 99.57 % for White; 0.42 % for Intermediate; 0.00 % for Black.

Therefore, the profile should be White.

Multinomial logistic regression
Predicted admixture:

White Intermediate Black
0.00 % 100.00 % 0.00 %
This individual is more than a billion (109) times more likely to be Intermediate rather than White.

Therefore, this individual is most likely to be Intermediate.
This individual is more than a billion (109) times more likely to be Intermediate rather than Black.

Therefore, this individual is most likely to be Intermediate.


Genetic distance algorithm
Finally, contributions Cgk sorted in descending order for your profile are:

White 51.21 % Skin colours
Intermediate 27.30 % Skin colours
Black 21.49 %

two type of tests say "white" and one says intermediate.

Bump. Im curious if any fully european person could get similar results to me especially if any fully european person could get intermediate on
