Incomplete values

Incomplete values (like 18.2, 24.3, 15.1 and such) are not supported in Internet version. Reason is simple: lists (one for every STR marker) does not have incomplete values in their contents, because it could be too heavy burden. Desktop edition of NevGen (not available on internet) does have support for incomplete values in its structures, code and data, and uses...

Priority in Athey’s predictor. Why there is no such thing in NevGen?

In Athey’s haplogroup predictor there is list box when user can select one of several areas: “Northwest Europe”, “South Europe”, “East Europe”, and others. Its effect on calculation of probability of some subclade is multiplying already multiplied frequencies of given haplotype’s alleles in subclade with subclade’s frequency in chosen area, before they are normalised with sum of them all. In...

False positives

Bayesian approach which NevGen predictor uses has one bad property, or problem: it assumes that entered haplotype belongs to one of subbranches supported by predictor. So it divides 100% of probability to its supported haplogroups. But this assumption need not be true in every case. No predictor is complete, it does not support every known haplogroup or subbranch. Beside that,...

About NevGen haplogroup predictor

First version of NevGen predictor was made in May of 2014. In that time it was available only as desktop application (and its existence was known only to small number of people in Serbia), and contained only part of today available subclades. Gradually during next two years many new subclades have been added, many existing subclades have been divided into...
