In TheoPannetier/comrad: R implementation of a Competitive Radiation model
dd_model_px R Documentation
Diversity-dependent model with power (p) dependence on speciation and
exponential (x) dependence on extinction
Description
A list specifying a DD model with power diversity-dependence on both the
speciation rate and extinction rate; to be fed as argument dd_model to
fit_dd_model_with_fossil(). This corresponds to the "exponential"
model found in DDD (ddmodel = 15) and elsewhere (e.g. BAMM).
Usage
dd_model_px()
Details
\lambda(N) = \lambda_{0} \times N^{-\frac{log\Big(\frac{\lambda_0}{\alpha(\lambda_0 - \mu_0) + \mu_0}\Big)}{log(K)}}
\mu(N) = \mu_{0}((1 - \alpha) + \alpha \frac{\lambda_{0}}{\mu_{0}})^{\frac{N}{K}}
