Compute Yule's Phi-coefficient

This function computes Yule's Phi-coefficient between the true and estimated block membership (its definition can be found here https://en.wikipedia.org/wiki/Phi_coefficient). In this context, the Phi Coefficient is a measure of association between two group membership vectors.

Usage

yule(z_star, z)

Arguments

z_star

a true block membership

z

an estimated block membership

Value

Real value of Yule's Phi-coefficient between the true and estimated block membership is returned.

Examples

data(toyNet)
yule(z_star = toyNet%v% "block",
                  z = sample(c(1:4),size = 200,replace = TRUE))
