Reference(s):

Criteria ? :

• Parsimony

Questions ? addressed by the method:

• Reconstruct state at all internal nodes (Reconstruct the optimal state, perhaps with uncertainty, of a particular character at all internal nodes on the tree (note that for likelihood, this category includes methods creating marginal and/or joint estimates)). Topic area: Reconstruct ancestor(s)
• Reconstruct state at one node (Reconstruct the optimal state, perhaps with uncertainty, of a particular character at one node (such as the root node)). Topic area: Reconstruct ancestor(s)

Character combinations ? addressed by the method:

• Multistate ordered-None-None

Software ? implementing the method:

• Mesquite (Mesquite is software for evolutionary biology, designed to help biologists analyze comparative data about organisms. Its emphasis is on phylogenetic analysis, but some of its modules concern population genetics, while others do non-phylogenetic multivariate analysis. Because it is modular, the analyses available depend on the modules installed. . Mesquite is not primarily designed to infer phylogenetic trees, but rather for diverse analyses using already inferred trees.) [open source]
