pbd_durspec_var {PBD}

Variance in duration of speciation under protracted birth-death model of diversification

Description

pbd_durspec_var computes the variance in the duration of speciation under the protracted speciation model for a given set of parameters

Usage

pbd_durspec_var(
    pars
)

Arguments

pars

Vector of parameters:

pars[1] corresponds to b (= la_3 in Etienne & Rosindell R2012) = speciation initiation rate
pars[2] corresponds to la_1 (= la_2 in Etienne & Rosindell 2012) = speciation completion rate
pars[3] corresponds to mu_2 (= mu_i in ER2012) = extinction rate of incipient species

Value

The variance in the duration of speciation
