What #RootsTech was Like for an #InnovatorShowdown Finalist - Blog comment by lkessler - 1 hr ago
We'll likely get to meet again Tony, somewhere, sometime. I don't go to RootsTech each year. I previously was there in 2012 and 2014. I usually need a good reason to go, and not being there for 3 years was my good reason.

Non-Matches by cM - Blog entry by lkessler - 1 Feb 2017
Roberta Estes did the first analysis of this and asked someone to do the same thing for an endogamous population. I had that data and I felt I wanted to know as well. I did a blog post about it a few days ago that I titled Double Match Phasing for an Endogamous Population, but using the term “Double Match ...

Triangulation, Single Matching and Double Matching - Blog entry by lkessler - 27 Jan 2017
It seems like my last post was a bit confusing to many people. I expect that the way I drew the boxes (to be segments) and the way I connected them with lines (indicating matching) was not intuitive, and it did not allow people to see that Double Matching with two people actually triangulates. I’m going to ...
Comparing Single Matching to Double Matching - Blog entry by lkessler - 25 Jan 2017

Double Match Triangulator - Version 1.4 - Blog comment by lkessler - 22 Jan 2017
Thanks, Jill. My motivational goal is really wanting the program to be able to figure out how some of these 7,000 DNA-relatives of mine are actually related to me. I think ultimately, I can get the program to do it. Slowly getting there. Louis
Double Match Filtering for an Endogamous Population - Blog entry by lkessler - 22 Jan 2017
A few days ago, Roberta Estes posted: Concepts – Segment Size, Legitimate and False Matches where she compared a child’s matches against those of her parents. She downloaded the Chromosome Browser Results (CBR) file from FamilyTreeDNA for a set of parents and a child, and then explained how she did the ...
