I did tmrca for the whole 20 or so haplotypes of the clade you are in, and got tmrca = 1900 years with sigma of 300 years. -----Original Message----- From: Roy Silfven Sent: Tuesday, November 22, 2011 12:56 PM To: y-dna-haplogroup-i@rootsweb.com Subject: [yDNAhgI] Sigmas for TMRCA estimates Ken and all ~ Having no skill at this sort of stuff, I never the less jumped into the gap. I entered values for 3 guys and myself from the AS9b (AS16 per Ken): Kits U2614, 192971, 121192, 154151. We are a rather tight group at 67 markers, the closest is a GD of 2 and a max GD of 5. Three of us claim our most distant male ancestor from Finland c. 550-510 YBP and one of us is Scottish with likely links to Viking Norway. Did I do it right? My initial guess age estimate was 800. My first result at BV529 was 9.9013. The second iteration was 9.8300032. I’m not sure of the relevance but the SigimaG= at BY529 is 6.90363.
