sample_sbm {mlsbm}

R/Rcpp function for sampling from a single level stochastic block model

Description

This function allows you to sample a single level stochastic block model.

Usage

sample_sbm(z, P)

Arguments

z

An n x 1 vector of community labels for each node

P

A K x K symmetric matrix of community connectivity probabilities

Value

An adjacency matrix

Examples

n = 100
K = 3
pi = rep(1/K,K)
z = sample(1:K, size = n, replace = TRUE, prob = pi)
p_in = 0.50
p_out = 0.05
P = matrix(p_out, nrow = K, ncol = K)
diag(P) = p_in
A = sample_sbm(z,P)
