In Shimodaira–Hasegawa Test, The degree of freedom used for the analysis depends on the substitution model used. It relies on the following test formula d = 2(ln LA – ln LB) = 2 ln(LA/LB). Here, is the log likelihood ratio score and ln LA and ln LB are likelihood scores for tree A and tree B, respectively.
The KH test sets out to test the null hypothesis that the two competing tree topologies are not significantly different.
In phylogenetic analysis, it is also important to test whether two competing tree topologies can be distinguished and whether one tree is significantly better than the other.
