【摘要】：盲态审核是数据管理与统计分析的衔接环节,盲态审核对数据质量应从数据管理和统计的角度综合予以考虑。盲态审核阶段对试验数据进行最终的稽查和质量评价有助于保证经过数据管理后提交的数据能达到统计分析的质量要求;对方案违背和/或偏离情况的分析和评价是研究结论科学可靠的必要保证,同时也为后续的统计分析中数据质量问题的处理提供了参考。
[Abstract]:Blind auditing is the link between data management and statistical analysis. Blind auditing should consider data quality comprehensively from the point of view of data management and statistics. The final audit and quality evaluation of the test data at the stage of blind audit is helpful to ensure that the data submitted after data management can meet the quality requirements of statistical analysis. The analysis and evaluation of the scheme violation and / or deviation is the necessary guarantee for the scientific and reliable conclusion of the study, and it also provides a reference for the treatment of the data quality problems in the subsequent statistical analysis.
