⚠️There's a newer version (5.2.2) of this package.Take me there.

DDD (version 0.4)

Diversity-dependent diversification

Description

DDD implements maximum likelihood methods based on the diversity-dependent birth-death process to test whether speciation or extinction are diversity-dependent. See Etienne et al. 2011, Proc. Roy. Soc. B, doi: 10.1098/rspb.2011.1439.
