ergm 4：新功能
ergm 4: New features
摘要：
ergm包支持网络数据的统计分析和模拟。它锚定了2008年《统计软件杂志》特刊中介绍的用于R网络分析的statnet套件。本文概述了ergm版本4 2021中的新功能。这些措施包括更灵活的处理节点协变量，长期运营商，扩展和简化模型规范，新的模型，网络与价值的边缘，改善处理网络的样本空间的约束，估计与丢失的边缘数据。我们还确定了statnet套件中的新软件包，这些软件包将ergm的功能扩展到其他网络数据类型和结构特征，以及支持statnet开发过程和应用程序的强大在线资源集。
英文摘要：
The ergm package supports the statistical analysis and simulation of network data. It anchors the statnet suite of packages for network analysis in R introduced in a special issue in Journal of Statistical Software in 2008. This article provides an overview of the new functionality in the 2021 release of ergm version 4. These include more flexible handling of nodal covariates, term operators that extend and simplify model specification, new models for networks with valued edges, improved handling of constraints on the sample space of networks, and estimation with missing edge data. We also identify the new packages in the statnet suite that extend ergm's functionality to other network data types and structural features and the robust set of online resources that support the statnet development process and applications.
