最近正在关注分类变量有多重响应问题时的卡方分析,先是看了国外文献,也看过楼主的资料了,总结一句话:楼主或者国内的普遍分析方法都不严谨。大家要想严谨地分析多重响应分类变量的独立性或比例差异,还是参考一些英文文献吧。在此引用一句证明相关资料的不严谨之处:If respondents are allowed to pick only 1 out of c responses, the hypothesis test may be performed using the Pearson chi-square test of independence. However, since respondents may pick more or less than 1 response, the test's assumptions that responses are made independently of each other is violated.
