通过共同起草和共同发起法案形成的政策网络反映了立法者在任职期间发展的最重要的联系类型之一。我们预计，在总统制国家，两名立法者之间的关系的可能性应该受到党派成员，领土联系和他们发展专业知识的政策领域的影响。考虑到关系数据的复杂性和账单发起网络的特殊性，我们提出了一种新的方法-使用反映领带频率的增强数据自举指数图模型-来解决稀疏密集网络的挑战。
Policy networks formed by co-authoring and co-sponsoring bills reflect one of the most important types of connection legislators develop while in office. We expect that in presidential countries, the probability of a tie between two legislators should be influenced by partisan membership, territorial linkages and the policy areas in which they develop expertise. Given the complex nature of relational data and the particular characteristics of bill initiation networks, we propose a new approach – bootstrapping an exponential graph model using augmented data reflective of the frequency of ties – to address the challenges of thinning dense networks.
