Techniques of statistical analysis developed for the analysis of experiments, for which the usual precautions of randomization ensure independence, are not necessarily appropriate to the analysis of epidemics. An outbreak of Q Fever in a Swiss Alpine valley previously reported in the International Journal of Epidemiology is analysed to make this point.
为实验分析而开发的统计分析技术，通常通过随机化预防措施确保独立性，但这些技术不一定适用于流行病分析。本文通过分析先前发表在《国际流行病学杂志》上的瑞士阿尔卑斯山谷Q热疫情来阐述这一点。
