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. 2012, Proc. Roy. Soc. B 279: 1300-1309, doi:
10.1098/rspb.2011.1439. DDD also implements a maximum
likelihood method to detect key innovations defined as
decoupling of diversity-dependence. See Etienne & Haegeman
