Assessing Identification Risk in Survey Microdata Using Log-Linear Models
使用对数线性模型评估调查微观数据的再识别风险
This article considers the assessment of the risk of identification of respondents in survey microdata, in the context of applications at the United Kingdom (UK) Office for National Statistics (ONS). The threat comes from the matching of categorical “key“ variables between microdata records and external data sources and from the use of log-linear models to facilitate matching. While the potential use of such statistical models is well established in the literature, little…
