Sampling from a hierarchical stochastic block model of networks.
sample_hierarchical_sbm(n, m, rho, C, p)
n |
Integer scalar, the number of vertices. |
m |
Integer scalar, the number of vertices per block. |
rho |
Numeric vector, the fraction of vertices per cluster, within a
block. Must sum up to 1, and |
C |
A square, symmetric numeric matrix, the Bernoulli rates for the
clusters within a block. Its size must mach the size of the |
p |
Numeric scalar, the Bernoulli rate of connections between vertices in different blocks. |
