论文摘要
我们考虑了在Katz，King和Rosenblatt（2020）中澄清和开发的政治学文献中提出的党派对称性的衡量标准。基本的数学操纵表明对称指标具有令人惊讶的属性，使其有意义。为了伴随一般分析，我们研究了党派对称性的衡量标准，这些措施在犹他州，德克萨斯州和北卡罗来纳州的最新投票模式方面，在每种情况下都提出了问题。综上所述，这些观察结果应引起人们对党派对称性定量分数的可用技术的主要关注点 - 包括平均米迪安分数，党派偏见得分和更一般的“党派对称标准” - 十年期的重新分配开始。
We consider the measures of partisan symmetry proposed for practical use in the political science literature, as clarified and developed in Katz, King, and Rosenblatt (2020). Elementary mathematical manipulation shows the symmetry metrics to have surprising properties that call their meaningfulness into question. To accompany the general analysis, we study measures of partisan symmetry with respect to recent voting patterns in Utah, Texas, and North Carolina, flagging problems in each case. Taken together, these observations should raise major concerns about the available techniques for quantitative scores of partisan symmetry -- including the mean-median score, the partisan bias score, and the more general "partisan symmetry standard" -- as the decennial redistricting begins.
