Entropy (degree corrected)

Calculate the degree corrected entropy associated with the current graph and block partition.

Usage

entropy_corrected(E, d, directed = FALSE)

Arguments

E

Integer matrix of edge counts associated with current partition.

d

List with one or two integers vector of node degrees.

directed

Whether graph is directed

Details

Undirected case:

$$ S_c = - E - \sum_k N_k \ln k! - \frac{1}{2} \sum_{rs} e_{rs} \ln\left(\frac{e_{rs}}{e_r e_s}\right) $$
