In ergmclust: Exponential-Family Random Graph Models for Network Clustering

C++ function for updating the gradient function in a static binary directed network.

Description

The C++ function grad_HMM_stat_dir_oe() updates the gradient function when the number of clusters is greater than or equal to 2 in a static binary directed network. (The above description may need further improvement.)

Usage

grad_HMM_stat_dir_oe(theta, gamma, network, N, K)

Arguments

theta	Vector of current theta (network canonical parameters) values.
gamma	Vector of current gamma (variational parameters) values.
network	Array of a network adjacency matrices.
N	Number of nodes.
K	Number of clusters.

Value

Returns the gradient vector of ELBO with respect to theta parameters for Newton-Raphson update in the M-step.
