The ambiguity of many sets of cohort data is illustrated by cohort data on drinking alcoholic beverages from American national surveys conducted during the late 1950s, late 1960s, and late 1970s. Although the data approximate the pattern predicted by pure linear cohort effects, examination of "side information" reveals that they are likely to reflect positive period effects offset from one date to the next by negative age effects. Researchers are cautioned that all available "side information" should be considered before statistical cohort models are tested. Some researchers have tried to use tests of statistical models to answer questions which must be answered before appropriate statistical tests can be applied.
20世纪50年代末、60年代末和70年代末美国全国性调查中关于饮用酒精饮料的队列数据说明了许多组队列数据的模糊性。尽管这些数据接近纯线性队列效应预测的模式,但对“辅助信息”的审查表明,它们可能反映了正的时期效应,且这些效应因负的年龄效应而从一个时间点偏移到下一个时间点。研究人员被提醒,在测试统计队列模型之前应考虑所有可用的“辅助信息”。一些研究人员试图使用统计模型检验来回答在应用适当的统计检验之前必须回答的问题。
