Title : new Usage : my $obj = new Bio::Tree::Statistics(); Function: Builds a new Bio::Tree::Statistics object Returns : Bio::Tree::Statistics Args :
Title : fu_and_li_D Usage : my $D = $statistics->fu_an_li_D($tree,$nummut); Function: For this we assume that the tree is made up of Bio::Tree::AlleleNode's which contain markers and alleles each marker is a 'mutation' Returns : Fu and Li's D statistic for this Tree Args : $tree - Bio::Tree::TreeI which contains Bio::Tree::AlleleNodes
