accelerated transformation (ACCTRAN)
Glossary of "Cladistics (2nd ed.)" by Kitching et al. (1998)
- A procedure for resolving ambiguous optimization in which the initial forward character transformations are placed on to the cladogram as close to the root as possible. Accelerated transformation accounts for homoplasy in terms of reversals to the plesiomorphic condition. Also known as fast transformation. Cf. delayed transformation.
