WebGeneralized dissimilarity modeling (GDM) GDM is a distance-based method, so we will first need to generate a genetic distance measure among individuals. We will simply use Euclidean distance, but if you had populations as sample points you could use pairwise Fst or other widely used measures in genetics. We first estimate genetic (Euclidean ...
