Charles and all:

Does anyone know how in the AncestrybyDNA calculations calculations using Charles' log, how they would treat someone like my uncle who expected 6% Native American and received a result of 8% East Asian; or a cousin of the same generation who received 5% Native American and 4% East Asian? I am wondering whether they consider expecting NA and receiving EA results to be a validation of their test. Of course if this is true then this would skew their statistical findings in a direction that best suits their purposes - circumventing the "sticky wicket" of the East Asian "problem".

John and Malcolm,

Thank you for your reviews of the new "Accuracy and Precision" section
of AncestrybyDNA's new website in regards to their recent statistical
analysis of the DNAPrint Test Results Log entries.

John, from your comments and Malcolm Dodd's comments it appears that
DNAPrint has taken the data in the Log and statistically selectively
massaged it in such a way as to deliberately make it look like the vast
majority of people taking the DNAPrint test obtained results very close
to what they expected from their genealogical research, and thus
implying that the test is very accurate and precise. I believe we know
that is not true. <clipped>
