Distance based methods include two clustering based algorithms, UPGMA, NJ, and two... WebThe sum of squares is printed out, and if P = 2.0 Fitch and Margoliash's "average percent standard deviation" is also computed and printed out. This is the sum of squares, divided by N-2, and then square-rooted and then multiplied by 100 (n is the number of species on the tree): APSD = ( SSQ / (N-2) )1/2 x 100.
