Pickett and Randle (2005) showed that for n > 4 taxa, any prior probability distribution that is uniform with respect to tree topologies induces a non-uniform distribution on clades. Steel and Pickett (2006) then strengthened this result by proving that any label invariant distribution on trees induces a non-uniform prior on clades, but left open the possibility of a uniform distribution on clades that is not label invariant. The point of this letter is to show that uniform priors on clades are… CONTINUE READING
