诚恳的请教各位:
我写毕业论文,参考别人的问卷进行修改,预调研数据收回后,用SPSS做信度分析,克朗巴哈系数很高,有0.982,结果出现 Warnings
The covariance matrix is calculated and used in the analysis.
The determinant of the covariance matrix is zero or approximately zero. Statistics based on its inverse matrix cannot be computed and they are displayed as system missing values.
我是统计菜鸟,不明白哪里出现了问题,以及该如何解决。
恳请各位统计前辈,牛牛,帮我解答下吧,我的问题出现在了哪里?以及我该从哪些方面解决问题。衷心感谢您的热心帮助
