Test of Diversification-Shift With the Yule Process

This function performs a test of shift in diversification rate using probabilities from the Yule process.

Keywords
htest
Usage
richness.yule.test(x, t)
Arguments
x

a matrix or a data frame with at least two columns: the first one gives the number of species in clades with a trait supposed to increase or decrease diversification rate, and the second one the number of species in the sister-clades without the trait. Each row represents a pair of sister-clades.

t

a numeric vector giving the divergence times of each pair of clades in x.

Value

a data frame with the $\chi^2$, the number of degrees of freedom (= 1), and the P-value.
