\title{
A Suite of Packages for the Statistical Modeling of Network Data
}
\description{
\pkg{statnet} is a suite of software packages for statistical network analysis.
The packages implement recent advances in network modeling based on
exponential-family random graph models (ERGM), as well as latent space
models and more traditional network methods. The components of the package
provide a comprehensive framework for ERGM-based network modeling: tools for
model estimation, for model evaluation, for model-based network simulation, and
for network visualization. This broad functionality is powered by a central
Markov chain Monte Carlo (MCMC) algorithm. The coding is optimized for speed
and robustness.
}
\details{
\pkg{statnet} packages are written in a combination of \R and
\code{C} It is usually used interactively from within the \R graphical
user interface via a command line. it can also be used in
non-interactive (or ``batch'') mode to allow longer or multiple tasks
to be processed without user interaction. The suite of packages are
available on the Comprehensive \R Archive Network (CRAN) at
\url{http://www.r-project.org/} and also on the \pkg{statnet} project
website at \url{http://statnet.org/}
The \pkg{statnet} suite of packages has the following components:
\itemize{
\item \pkg{ergm} is a collection of functions to fit, simulate from,
plot and evaluate exponential random graph models. The main
functions within the \pkg{ergm} package are
\code{\link[ergm]{ergm}}, a function to fit linear exponential
random graph models in which the probability of a graph is dependent
upon a vector of graph statistics specified by the user;
\code{simulate}, a function to simulate random graphs using an ERGM;
and \code{\link[ergm]{gof}}, a function to evaluate the goodness of
fit of an ERGM to the data. \pkg{ergm} contains many other functions
as well.
\item \pkg{tergm} is a collection of extentions to \pkg{ergm}
enabling it to fit models for dynamic networks.
\item \pkg{ergm.count} is an extension to \pkg{ergm} enabling it to
fit models for networks whose relations are counts.
\item \pkg{ergm.userterms} provides a template for implementing new
ERGM terms.
\item \pkg{sna} is a set of tools for traditional social network
analysis.
\item \pkg{degreenet} is a package for the statistical modeling of
degree distributions of networks. It includes power-law models such
as the Yule and Waring, as well as a range of alternative models
that have been proposed in the literature.
\item \pkg{latentnet} is a package to fit and evaluate latent position
and cluster models for statistical networks The probability of a tie
is expressed as a function of distances between these nodes in a
latent space as well as functions of observed dyadic level
covariates.
%% \item \pkg{netperm}: A package for permutation Models for relational
%% data. It provides simulation and inference tools for exponential
%% families of permutation models on relational structures.
\item \pkg{networksis} is a package to simulate bipartite graphs
with fixed marginals through sequential importance sampling.
\item \pkg{relevent} is a package providing tools to fit relational
event models.
\item \pkg{network} is a package to create, store, modify and plot
the data in network objects. The \code{\link[network]{network}}
object class, defined in the \pkg{network} package, can represent a
range of relational data types and it supports arbitrary vertex /
edge /graph attributes. Data stored as
\code{\link[network]{network}} objects can then be analyzed using
all of the component packages in the \pkg{statnet} suite.
\item \pkg{networkDynamic} extends \pkg{network} with functionality
to store information about about evolution of a network over time,
defining a \code{\link[networkDynamic]{networkDynamic}} object
class.
}
In addition, the following packages are available from the author:
\itemize{ \item \pkg{rSonia}: provides a set of methods to facilitate
exporting data and parameter settings and launching SoNIA (Social
Network Image Animator). SoNIA facilitates interactive browsing of
dynamic network data and exporting animations as a QuickTime movies.
}
\pkg{statnet} is a metapackage, depending on all of the above
packages, so that they can be installed together.
Each of these components is described in detail in the references
below. Loading the \pkg{statnet} package into \R automatically
loads them all. Each package has associated help files and internal
documentation that is supported by the information on the Statnet
Project website (\url{http://statnet.org/}). A tutorial, support
mailing list, references and links to further resources are provided
there.
When publishing results obtained using this package the original
authors are to be cited as described in
\code{citation("statnet")}. In addition, please cite the specific
package that you use.
We have invested a lot of time and effort in creating the
\code{statnet} suite of packages for use by other researchers.
lease cite it in all papers where it is used.
