WebSep 9, 2012 · NSsites = 1 (which allows 2 categories for sites: purifying and neutral). Site model M2a (positive selection): model = 0 (dN/dS doesn't vary on branches) NSsites = 2 (which allows 3 categories for sites: purifying, neutral and positive selection). Then we can compare M1 and M2a by the likelihood ratio test. Example 2: Branch model M0: http://web.mit.edu/6.891/www/lab/pamlDOC.pdf
