Latent position and cluster models for networks

Description

The package latentnet is used to fit latent cluster models, where the probability of a network g, on a set of nodes is a product of dyad probabilities, each of which is a GLM with linear component eta_{i,j}=sum_{k=1}^p β_k X_{i,j,k}+||Z_i-Z_j||, where X is an array of dyad covariates, β is a vector of covariate coefficients and Z_i is the latent space position of node i.

The ergmm specifies models via: g ~ <model terms> where g is a network object For the list of possible <model terms>, see terms.ergmm.

Details

The arguments in the ergmm function specific to latent variable models are ergmm.control. See the help page for ergmm for the details.

The result of a latent variable model fit is an ergmm object. Hence the summary, print, and plot functions apply to the fits. The plot.ergmm function has many options specific to latent variable models. See the help page for plot.ergmm for the details.

Value

ergmm returns an object of class 'ergmm' that is a list.
