立法投票记录是关于立法者偏好、党内凝聚力和各种政策问题分歧的重要信息来源。分析立法投票记录的标准方法在应用于立法机构时往往会有严重的缺陷，例如英国下议院，其特点是高度纪律性的政党，战略性投票和大量缺失的数据。我们提出了一种方法（基于Dirichlet过程混合模型），用于分析这种投票记录，不遭受这些相同的问题。我们的方法是基于模型的，因此允许一个概率的声明有关的数量感兴趣。它允许人们估计一个政党或任何其他议会成员（MP）团体内的投票集团数量。最后，它既可以用作预测模型，也可以用作探索模型。我们说明了这些点，通过应用该方法的工党议员在1997-2001年届英国的投票记录。下议院。
Legislative voting records are an important source of information about legislator preferences, intraparty cohesiveness, and the divisiveness of various policy issues. Standard methods of analyzing a legislative voting record tend to have serious drawbacks when applied to legislatures, such as the United Kingdom House of Commons, that feature highly disciplined parties, strategic voting, and large amounts of missing data. We present a method (based on a Dirichlet process mixture model) for analyzing such voting records that does not suffer from these same problems. Our method is model-based and thus allows one to make probability statements about quantities of interest. It allows one to estimate the number of voting blocs within a party or any other group of members of parliament (MPs). Finally, it can be used as both a predictive model and an exploratory model. We illustrate these points through an application of the method to the voting records of Labour Party MPs in the 1997–2001 session of the U.K. House of Commons.
