为了保证食品安全风险监测数据处理、分析的合理性和科学性,获得可靠的结果,对低于检出限数据的处理、率的比较、样本类别的分组所适用的统计分析方法进行探讨。总结了食品安全风险监测数据的性质及特点,阐明了按特定研究目的数据处理分析所适用的统计分析方法,按特定的分析目的选择合适的统计分析方法,从而获得可信、可靠和可比的结果,为监测提供有力的数据支持。避免盲目的运用统计分析方法评价分析食品安全风险监测数据,进而导致评价结果偏差或错误,误导政府决策、部门监管和消费者消费。
This article aims to promote the rational and scientific statistical analysis applied to food safety risk surveillance. The not-detected data, rate comparison, sample category and statistical analysis methods are discussed, and the characteristics of food safety risk surveillance data arc analyzed and summarized. It is very important to apply a suitable and correct statistic analysis to obtain reliable, credible and comparable results, which would provide powerful support for monitoring. Otherwise, the conclusion of food safety risk surveillance would mislead the government supervision decisions, and consumers＇ choices.
