Good points Vincent. I relied on what I found on the Cohen Project and
the Y-DNA J Project (Cohen subsection) as my guide. I did the histograms
for each marker. I calculated the modal. Then I went through my J1
database (271 haplotypes having 37/67 markers) looking for marker
mismatches (I ignored GD, I just looked for mismatches). This allowed me
to pick up a few extra cases, but I didn't feel comfortable going beyond
about 15 mismatches (15 with 67 markers, 8 with 37 markers (actually I
went up to 9 as after examining the specific cases they looked ok to
me)). I thought then of writing a Bayesian clade predictor program
which would allow to dig deeper in mismatches with more confidence. If
you check the file I sent (column CD, "FTDNA Project") you'll see that
most of the data is directly from the Cohen DNA or Y-DNA J (Cohen
subsection) projects, they were basically my main guide. I know it isn't
very scientific, but it is the best we have.
I didn't think about that second point. It could be a problem. Bias is
difficult to overcome sometimes :-(
