SDR 1.0 Master Box

SDR 1.0 Master Box is an outcome of the project \"Democratic Values and Protest Behavior: Data Harmonization, Measurement Comparability, and Multi-Level Modeling in Cross-National Perspective\". It consists of five data files and corresponding documentation: (1) the master file (MASTER) with individual-level data from cross-national surveys, (2) country-level file (PLUG-COUNTRY), (3) country-year-level file (PLUG-COUNTRY-YEAR), (4) survey-level file (PLUG-SURVEY), and (5) wave-level file (PLUG-WAVE). The MASTER file is the core of the Master Box and contains harmonized target variables, harmonization control variables, as well as flags for non-unique records, non-unique case IDs, and missing case IDs, while the other PLUG files containing contextual data, metadata, and data quality indicators. 2018/08/22 We have identified some errors in the SDR 1.0 data.

SDR 1.0主数据集包是项目"民主价值观与抗议行为：跨国视角下的数据协调（data harmonization）、测量可比性与多层建模"的产出成果。该数据集包包含5个数据文件及配套文档：(1) 主文件（MASTER），收录跨国调查的个体层面数据；(2) 国家层面文件（PLUG-COUNTRY）；(3) 国家-年份层面文件（PLUG-COUNTRY-YEAR）；(4) 调查层面文件（PLUG-SURVEY）；(5) 波次层面文件（PLUG-WAVE）。其中主文件是该数据集包的核心，包含经协调的目标变量、协调控制变量，以及非唯一记录、非唯一案例ID与缺失案例ID的标记字段；其余PLUG系列文件则收录情境数据、元数据与数据质量指标。2018年8月22日，我们在SDR 1.0版本数据中发现了部分错误，具体信息请参阅https://dataharmonization.org/data/sdr-data-alerts/。
