Disclosure risk assessment for microdata sets and its application to the official statistics

研究了几种用于微数据集风险评估的超总体模型的性质。将规模指标扩展到多指标，对由两次或多次抽样得到的微观数据集或由分层抽样得到的微观数据集进行风险评估。基本建立了多总体大小指标的非参数估计方法。交换方法是表格数据的公开控制过程之一。发展了马尔可夫基交换法的理论。

The properties of several superpopulation models which are used for assessing the risk of a microdata set, were investigated. The size indices were extended to the multi-indices, to carry out the risk assessment for the microdata sets which had been made from the samples on two or more occasions, or a microdata set which had been made from a stratified sample. The nonparametric estimation method for the multi-population size indices was almost established. The swapping method is one of the disclosure control procedures for a tabular data. The theory of swapping method using Markov bases was developed.
