is_negative

Data frame representing path overlaps, typically generated
by <code><a rd-options="" href="/link/all_path_overlaps?package=admixturegraph&version=1.0.2" data-mini-rdoc="admixturegraph::all_path_overlaps">all_path_overlaps</a></code>.

overlaps


All overlaps are either empty or have a negative weight.


Implements tools for building and visualising admixture graphs
and for extracting equations from them. These equations can be compared to f-
statistics obtained from data to test the consistency of a graph against data --
for example by comparing the sign of f_4-statistics with the signs predicted by
the graph -- and graph parameters (edge lengths and admixture proportions) can
be fitted to observed statistics.
