Quarnet GoF –or simply QGoF
QuartetNetworkGoodnessFit.jl is a Julia package for phylogenetic networks analyses using four-taxon subsets. It includes tools to measure the goodness of fit of a candidate network to data on subsets of 4 tips. It depends on the PhyloNetworks package.
For a tutorial, see the manual:
- goodness of fit of a candidate network
- quartet concordance factor simulation
- expected concordance factors
