The study of homicide by police (HbP) has been hampered by measurement error in existing data. This study draws from three separate flawed data systems and uses confirmatory factor analysis (CFA) to quantify and correct for these errors. Results show that the CFA models presented can be used to construct more valid and reliable measures of sub-national HbP rates. The improved measures are useful for conducting analyses of causes and correlates of HbP. The implications of these findings for future research are discussed.

运用多种缺陷措施构建警察有效有效的命案率

现有数据中的测量误差阻碍了警察对凶杀的研究。这项研究来自三个独立的有缺陷的数据系统，并使用验证性因子分析（CFA）来量化和纠正这些错误。结果表明，提出的CFA模型可用于构建次国家HbP率的更有效和可靠的度量。改进的措施对于进行HbP的原因和相关性分析很有用。讨论了这些发现对未来研究的意义。
